Movie Monday: ‘Killer’ Whales

“A fish tougher and more terrible.”

At a quarter past twelve on 9 March 1976, some 560 miles north of the equator and a very long way from anyone, something hit the bow of the yacht Guia III hard enough to shift it three metres sideways.

Claudio Cuoghi was at the helm and had felt nothing coming. By the time Giorgio Di Mola got below, the forward compartment was already full. The breach was well beneath the waterline and far too large to plug; two spinnaker bags stuffed into it were sucked straight back out, taking a crewman’s arm most of the way with them. Sails passed under the hull were torn away. The batteries went under before a proper mayday could get out. Jérôme Poncet, skippering that leg of the Atlantic Triangle, said afterwards that not even God could have saved her.

She sank bow-first. The crew got into an inflatable with fourteen litres of water between them and were picked up around midnight the following day, having fired flares at a passing ship. Within the week they were at the Waldorf Astoria as guests of Whitbread, which was rather the point of the race in the first place.

There were five orcas around the boat while she went down. One of them lay against the hull, entirely still, in a posture that Francesco Longanesi Cattani could only describe as the animal trying to work out what sort of creature Guia was. On deck, another crewman was shouting that the whale had come to murder them. When the yacht finally went under, the orcas left.

Two readings of the same animal, in the same four minutes, from men standing five feet apart. One of them describes an intelligent predator investigating an unfamiliar object. The other describes a monster. Fifty years on we are still choosing between them, and the record of which one we picked, and when, and why, is largely a record of what was showing at the cinema.

The killer, dismissed

Before the orca could be a monster, it had to be worth noticing, and for most of the written record it was not.

The sixteenth-century naturalists were happy enough with sea monsters in the abstract — Konrad von Gesner and Ulisse Aldrovandi both produced cetaceans of extravagant proportions, ship-devouring things with fountains erupting from their skulls — but these were whales in general, monstrous by category rather than by species. The orca had no particular billing.

Melville, three centuries later, gives it a paragraph and a shrug. In the Cetology chapter of Moby-Dick, Ishmael admits that the Nantucketer knows little of this whale and the naturalist nothing at all. He allows that it is savage, that it will fasten onto the lip of a larger whale and hang there like a leech until the bigger animal is worried to death. Then he loses interest. The killer is never hunted, he notes, and he has no idea what sort of oil it yields. He objects to the name on grounds of imprecision, and delivers the line that has outlived the rest of the passage by a comfortable margin: For we are all killers, on land and on sea; Bonapartes and sharks included.

There is something almost funny about this. The monster slot in the greatest whaling novel ever written goes to the sperm whale — an animal that mostly wants to be left alone in the dark eating squid — while the actual apex predator of the world ocean gets four sentences and a note that nobody bothers with it.

What did exist was testimony, and the testimony has always been more interesting than the fiction.

Two Inuit elders in the Foxe Basin passed on an account of a young man in 1955 who ignored advice about the thinness of the ice over Grand Suttie Bay, walked out over a polynya where orcas were trapped, and was taken when the whales deliberately broke the ice beneath him. It is oral history, it cannot be verified, and it is entirely possible that it is a cautionary tale about listening to your elders wearing a whale as a costume. But it should not be waved away either. It comes from people who lived and hunted alongside these animals in conditions no marine biologist has ever worked in, and it describes something behaviourally coherent — orcas breaking ice from below is documented hunting behaviour, not invention.

We have a photograph of very nearly the same thing. In the early 1910s, during the Terra Nova expedition, a pod of Antarctic pack-ice orcas made a determined attempt to wave-wash a photographer and a team of sledge dogs off an ice floe. Pack-ice orcas specialise in washing seals off floes. The dogs were barking. Nobody was hurt, and the modern reading is that the whales were doing exactly what they always do, to what they reasonably believed were seals.

And then, in the space of four months in 1972, the two incidents that ought to have given anyone writing a killer whale film all the material they needed.

In June, Dougal Robertson’s forty-three-foot schooner Lucette was struck by orcas 200 miles west of the Galápagos and sank in about a minute, putting his family into a raft and a dinghy for thirty-seven days before a Japanese fishing boat found them. In September, an eighteen-year-old surfer named Hans Kretschmer was bitten on the leg at Point Sur in California, taking something close to a hundred stitches. His doctor reportedly said it looked as though somebody had gone at his thigh with an axe.

Kretschmer’s case is the only documented instance of a wild orca injuring a human being. It is also, on inspection, the case for the defence. There were sea lions in the water. He punched the animal’s head, and it let go. He then bodysurfed to shore expecting a second strike that never came. The pattern — a single investigative bite followed by immediate release — is far more legible now than it was in 1972. The one time an orca ever laid teeth on a human in the wild, it appears to have realised its mistake and spat him out.

That is the whole evidentiary record, more or less, as it stood in the mid-1970s. A sunken schooner. A bitten surfer. Some Edwardians on an ice floe. An unverifiable story from the Canadian Arctic. Against it: an animal that had, by then, been netted, sold, towed, penned and taught to jump through hoops for the better part of a decade, and had done almost nothing about it.

Hollywood was about to fix that.

The gentle giant, and what he built

In June 1965, a young male orca drifted into a salmon net near the village of Namu in British Columbia. The fisherman who found him rang Ted Griffin, who owned the Seattle Marine Aquarium, and Griffin bought the whale for eight thousand dollars, which turned out to be the cheapest part of the exercise. Namu was towed 450 miles south in a floating pen. Crowds lined the Seattle waterfront. Aircraft circled.

Namu became the first captive orca to perform in the water with a person, and Griffin — riding him in front of paying audiences — became a local hero. There was a film, Namu, the Killer Whale, made by United Artists in 1966, in which a marine biologist befriends a misunderstood whale and must persuade frightened fishermen that the animal is gentle. There was a theme song. There was, in the space of about eighteen months, a wholesale reversal of the killer whale’s public reputation from oceanic vermin to enormous friendly dog.

Namu died on 9 July 1966, having survived just over a year. He had picked up a bacterial infection from the polluted water of his pen; weakened, he became entangled in the cables of his enclosure and drowned. Griffin later said he wished the whale had succeeded in what he chose to describe as a break for freedom.

Here is the fact around which everything else in this essay orbits. The film that taught the world to love orcas is the film that built the industry that killed them. Demand for a Namu of one’s own was immediate and enormous. Griffin founded a whale-catching company to supply the marine parks; his best customer was SeaWorld. He took the calf who became the original Shamu, having harpooned her mother. By 1970 the Penn Cove captures were using boats, aircraft and explosives to round up young whales in Puget Sound, and four calves drowned in the nets. The bodies were weighted and sunk. They were found the next day.

None of this was a betrayal of the gentle-giant story. It was the direct commercial consequence of it. You cannot sell tickets to see a monster up close. You can sell an enormous number of tickets to see a friend.

Find me a fish

In the middle of the night in 1975, Dino De Laurentiis telephoned the screenwriter Luciano Vincenzoni. Vincenzoni admitted to having seen Jaws. De Laurentiis instructed him to go and find a fish tougher and more terrible than the great white.

Vincenzoni, by his own account, had no interest in marine life whatsoever. His brother Adriano, who did, pointed him towards killer whales. The orca is not a fish, but that has never been the sort of objection that slows a producer down.

What emerged was Orca, directed by Michael Anderson, shot largely around Petty Harbour in Newfoundland, released by Paramount in July 1977 on a budget of six or seven and a half million dollars, depending on whose accounting you trust, and taking $14.7 million. Ennio Morricone wrote the score, which is far better than the film deserves. Richard Harris plays the fisherman with the full-throated commitment of a man who has decided that if he is going to be in this, he is going to be in this. Charlotte Rampling is the marine biologist. Will Sampson, two years on from One Flew Over the Cuckoo’s Nest, is the Indigenous man who understands what the whale is doing. Bo Derek loses a leg, in case anyone had failed to spot which film was being remade.

The plot: Harris’s character harpoons a pregnant female orca. She miscarries on his deck, in a sequence still capable of clearing a room. Her mate then works through his boat, his livelihood and his town until the two of them can settle it on open water.

It is, of course, Moby-Dick turned inside out. Melville’s whale is a blank onto which Ahab projects everything; the horror is that we cannot know whether there is anything behind it. Vincenzoni’s whale has motive, grief, a plan, and something close to a legal case. The animal Melville could not be bothered to describe has become the only character in the film with a coherent inner life.

The phone call

Which brings us back to Guia III, and to the strangest document in this whole story.

In the weeks after the sinking, Giorgio Falck received a telephone call from Los Angeles. The caller introduced himself as a friend of Falck’s brother-in-law. He gave his name as Vincenzoni. He said he had been studying killer whales for three years and was writing a book about them.

He then told Falck a story. In New Zealand, a fishing boat had injured a female orca with its propeller. The male had sunk the boat — and he was careful with the detail, noting the vessel’s seventy-millimetre planking against Guia‘s thirty-five. A month later, in the same place, the same animal had killed a crew of six.

That is the plot of Orca, related as established fact, to a man who had just lost his boat, sixteen months before Paramount put it in cinemas.

I cannot prove that this was Luciano Vincenzoni, and I am not going to pretend otherwise. The claim of three years’ study sits awkwardly against a brief handed down in 1975, and it is at least possible that the caller was his brother Adriano, the one with the zoological interest. But the call came from Los Angeles. The surname is not common. The timing lands precisely inside the film’s development. And the anecdote is not merely similar to Orca‘s premise; it is Orca‘s premise, with the numbers filed off. On the balance of everything we know, this is the film being written, out loud, down a transatlantic line, to a survivor.

It is worth pausing on what that story actually asserts. Six people killed by a single orca would be, by a wide margin, the worst loss of human life to a killer whale ever recorded anywhere. It appears in no register, no report, no scientific literature. Somebody in Los Angeles in 1976 was collecting atrocity stories about killer whales, and either could not tell or did not care which of them were true.

And then Falck — who had every reason on earth to want a monster, who had just watched a boat he loved go down and who describes the orca as a hateful animal — refuses the story flat. He tells the caller he is perfectly aware sea monsters are in vogue since Jaws. He is aware that Guia‘s sinking is of interest chiefly because it happens to involve a topical one. But he is interested in boats and in racing, not in orcas and not in violence.

The man with the strongest possible claim on the revenge narrative would not take it. It was offered to him by a screenwriter, and he handed it back.

Yaka, Nepo, and the whales in the lorries

Orca was made with real whales, and this is where the film stops being merely silly and becomes something closer to evidence.

The two animals identified as the film’s leads are Yaka and Nepo. They were captured together on 11 December 1969 at Pender Harbour in British Columbia, when a group of twelve orcas — Northern Residents, a fish-eating population — was surrounded in a storm and six young animals taken. Yaka was around a year old. Nepo was around two. They were podmates. They were sold together, moved to Marine World in California on 28 December, and put in a tank with an older female called Kianu.

For a few years the three of them did well enough. Kianu grew possessive of Nepo and aggressive towards Yaka, and was sold to Japan in April 1978, which left the two survivors of the Pender Harbour capture alone together. The park hoped Yaka would breed. She never did.

Nepo died on 10 July 1980, of acute bronchopneumonia and kidney disease, at roughly twelve or thirteen years old. Yaka was beside his body and reportedly would not leave it, and afterwards stopped eating and stopped engaging with her trainers. A companion was brought in, an Icelandic female called Vigga, and the two of them performed together for over a decade. Yaka died on 29 October 1997 of a respiratory infection, having spent nearly twenty-eight years in tanks. She had been taken from the sea before she was old enough to have learned to hunt in it.

Marineland of the Pacific also supplied whales to the production, and the likeliest candidate there is Corky II, taken in the same 1969 round-up, though the crediting on this has been muddled for decades and I would not swear to the detail.

They are, by any reasonable measure, wonderful in the film. They are also, by any reasonable measure, giving away the entire game, because their dorsal fins have collapsed. It is a condition essentially unknown in wild males and rare in wild females, and near-universal in animals held long-term in tanks. It is on screen. In a film about a wild orca’s stolen family. In 1977. Nobody in the production appears to have thought it worth a comment.

Because the whales could obviously not be made to bite off Bo Derek’s leg or carry a corpse across a harbour, the effects team also built animatronic orcas out of rubber. These were good. They were good enough that when they were driven to set, animal rights activists blocked the lorries, believing there were live whales inside.

Sit with the shape of that for a moment. Protestors on a road in the mid-seventies, correctly identifying the crime, correctly identifying that whales were being trucked about for entertainment, and stopping entirely the wrong vehicle. The animals they were trying to save were not in the lorries. They were already at the park, already performing twice a day, and had been for six years. They would go on doing it for another twenty.

The door closes

Free Willy arrived in 1993 with a plot about a boy liberating a captive orca, and had the singular distinction of generating a real liberation campaign for its own star. Keiko had been captured off Iceland and was living in a small tank in Mexico City. Public pressure moved him to Oregon, then to Iceland, then to a sea pen; he eventually swam to Norway, where he died in 2003. Whether it worked depends entirely on what you thought it was for. He never rejoined a pod. He also spent his last years in the sea.

Then 2013, and Blackfish, and the argument was effectively over. What the film did was not reveal that captivity was cruel — people had been saying so since Namu — but connect the cruelty to the deaths of specific named human beings, and make the connection impossible to un-see. Every human being ever killed by an orca has been killed by a captive one. There is no confirmed fatal attack by a wild killer whale anywhere in the record, ever. The animal only becomes a man-killer inside a tank.

That is a devastating fact for a monster movie. It means the horror cannot be located in the animal. It can only be located in us.

The film that argues itself out of existence

Killer Whale arrived in January 2026, directed by Jo-Anne Brechin and co-written with Katharine E. McPhee, distributed by Lionsgate. Ceto is an orca held in a Thai marine park; after she kills a janitor, the management dumps her into the open sea. Two friends on holiday end up trapped in a lagoon with her.

On paper this should work. The premise carries genuine moral charge, the animal has a real grievance, and the audience arrives pre-loaded with everything Blackfish taught them. The film reviewed catastrophically — twenty per cent on the Tomatometer, and, more tellingly, twenty-one per cent with audiences.

The reviews are unusually consistent about why. Screen Rant found it succeeded as a sombre meditation on captivity and failed as a survival film, and concluded that the director was less interested in making something vicious than in condemning what had been done to the whale. Rue Morgue put its finger on the structural problem: the film cannot decide whether Ceto is an object of fear or of sympathy, and so makes the woman who cares most about her into her principal victim. The film even puts the argument for the defence into its own dialogue, noting that the only recorded fatalities have involved captive animals — a point one reviewer observed, drily, that nobody watching was going to care about.

So the received wisdom is that the captivity angle should have given the film an edge, and the evidence is that it did precisely the opposite. It disarmed it. You cannot frighten an audience with an animal they have already acquitted. The moment you explain why she is angry, you have converted your monster into a plaintiff, and the remaining eighty minutes become a courtroom drama in which everybody has already agreed on the verdict.

The orca is, I think, the only screen monster we have successfully talked ourselves out of. We know perfectly well that sharks are misrepresented and ecologically vital, and The Meg still took a billion dollars. We know bears are not malevolent and we still watch films about them eating people. But the orca’s rehabilitation was so recent, so total, and so specifically bound up in the story of its captivity that the monster no longer fits inside the animal. There is nowhere left to put it.

The revenge was always ours

And then, in May 2020, the whales started sinking boats.

Off the Iberian Peninsula, orcas began ramming vessels and biting the rudders off sailing yachts. By the middle of 2025 there had been more than 750 recorded encounters, over 250 boats damaged, and at least six sunk. The behaviour spread. The press adored it. The animals were assigned the collective designation “Gladis”, after Orcinus gladiator — whale-fighter — and the internet did what the internet does. They were called comrades by a labour organiser and by a newspaper columnist. Merriam-Webster announced that it welcomed its new Delphinidae overlords. A revenge fantasy that Paramount could not sell in 1977 was, in 2023, the most popular story in the world.

Except that it is not a revenge fantasy. It is fifteen animals.

The Iberian orcas are a genetically and culturally distinct subpopulation, listed by the IUCN as Critically Endangered since 2019, numbering fewer than forty individuals in total, and dependent on Atlantic bluefin tuna, which has its own problems. Around fifteen of them have taken part in the boat interactions: eleven juveniles and four adult females, with no identifiable ringleader. The rate is falling — 207 interactions in 2023, 136 in 2024, 125 the year after. Nobody has been hurt. Not once, in over 750 encounters. As GTOA’s Alfredo López has pointed out, they do not come in hard and sink the boat, which they could do easily if that were the objective.

Fifteen adolescent whales from a population smaller than a decent pub quiz turnout, most of them apparently playing, against which we have constructed an international narrative of maritime vengeance.

And here is the fact that ought to end the argument. Through the 1960s and 1970s, while Pacific orcas were being chased by aircraft, herded with explosives, netted, and stripped of their young — while Yaka and Nepo were being taken, sold, and put to work — those whales did not attack boats. Not one. There is almost no evidence that wild killer whales seek revenge at all. A chimpanzee robbed of food will retaliate. An aggrieved macaque will settle the score, sometimes against a relative of the offender. Orcas do not do this. The trainers killed in the parks were killed by animals that researchers believe were psychologically wrecked by the conditions they were kept in, which is not revenge either. It is something worse and much sadder.

The revenge was never theirs. We wrote it. We filmed it, using the actual victims as extras, in a park, for money. And half a century later, when a handful of bored teenagers off Cádiz started snapping rudders for reasons no one can establish, we recognised our own script and gave it a standing ovation.

The coda is uglier. Sailors are now carrying illegal firecrackers to throw at a critically endangered species. Some play death metal through speakers. Others bang steel bars against the hull. Marine mammal biologists are openly braced for someone to shoot one. The single population that has ever cost us anything is the one we are arming against, while the whales who genuinely had cause never lifted a fluke.

One of the six young orcas taken at Pender Harbour on that December night in 1969 is still alive. Corky II went to Marineland of the Pacific rather than Marine World, and to SeaWorld San Diego in 1987 when Marineland was bought and closed. She is around sixty-one. She has been in tanks for fifty-six years, longer than any orca in history. She was pregnant seven times and none of her calves lived past seven weeks. She has cataracts. She still performs.

Her siblings are alive in the water off British Columbia. When researchers played her family’s calls to her in 1993, after twenty-four years of captivity, she reacted so strongly that she was seen to shudder.

Melville thought the killer whale was hardly worth the ink. Namu made it loveable, and the loveliness built the tanks. De Laurentiis wanted a fish tougher and more terrible than the great white, and got a mammal that has never knowingly killed anybody. Killer Whale discovered in 2026 that you cannot run a monster movie on an animal the audience has already forgiven.

And a whale who is very probably in Orca is still swimming in circles in San Diego, forty-nine years after the film came out, having been cast as the monster in a story about her own abduction, and having never in fifty-six years done a single thing to deserve the part.

Monster Monday: The Mahamba

The Congo’s fifty-foot crocodile

Sometime in early 1888, a small government steamer was making four miles an hour up the Congo River when she ran aground. There’s nothing remarkable in that — Africa’s second longest river and the world’s deepest is a maze of shifting sandbanks, and any pilot expects to feel his hull kiss the bottom now and again. What was remarkable was that this sandbank began to heave. The water around the bow churned in a way no sandbank has any business doing, and the steamer’s engineer, leaning over to find the cause, watched the bank itself detach from the riverbed and bolt. It was a crocodile. One longer, he was certain, than his forty-two-foot boat, and it crossed the bar and tumbled into deep water before he could reach for a rifle. They had run the steamer clean into a living animal at speed, jammed it into the sand, and it had shrugged them off and left without a mark on it.

The engineer was John Reinhardt Werner, and the animal, if the Congo’s rivermen were to be believed, was the Mahamba.

A witness in the wrong century

Werner is an unusually good witness for a monster, which is precisely what makes him a problem. He was not a folklorist collecting tales around a fire, nor a Victorian showman selling a story. He was a working engineer keeping the boilers running on a colonial waterway, and he wrote his account up plainly in A Visit to Stanley’s Rear-Guard (Blackwood, 1889) as one observation among many practical ones. His steamer, the A.I.A., took her name from the Association Internationale Africaine — the “philanthropic” society, dedicated on paper to lighting the darkness of Africa and ending the slave trade, that served as Leopold II’s cover story while he assembled the private empire that would become one of the most murderous colonial regimes in history. I wanted to make that clear, because the romance of the Victorian riverboat curdles the moment you remember what the riverboat was for. Werner was part of the apparatus. His crocodile sightings come to us stamped with the flag of a project built on forced labour and mass death.

That grim provenance aside, Werner’s testimony is specific. He described these giant crocodiles as almost common on the river, and he did not hedge on size. On a low sand-spit beyond the grasses, he wrote, one might see a monster of perhaps fifty feet; he claimed to have seen several considerably longer than the A.I.A. On one occasion, stalking ducks across a sandbank with only a shotgun, he found the largest crocodile he had ever seen lying between him and his supper. Measuring it by eye against the steamer moored three hundred yards off, he reckoned it a full fifty feet long, with the ridged crest of its back standing four feet clear of the sand. He sent a boy for his rifle, thought better of the whole enterprise, and in retreating spooked the ducks — whereupon he took a shot at them, missed, and startled the crocodile into the water. It is a very funny, very human anecdote, and it has the ring of a man reporting exactly what he saw rather than embroidering a legend.

The scale problem

The Nile crocodile, the largest predator these waters officially hold, is a genuinely formidable animal that tops out at roughly twenty feet. A big saltwater crocodile — the largest living reptile on Earth — reaches perhaps twenty-one. Werner was describing something more than twice that length: a creature outside the entire range of any crocodile known to science, living or dead.

And that last phrase is where the Mahamba does something most cryptids cannot. It out-measures the fossil record.

The usual yardstick reached for here is Sarcosuchus imperator, the Cretaceous giant nicknamed the “SuperCroc.” When Paul Sereno’s team described it for a rapt public in 2001, the headline figure was around forty feet — a crocodile-shaped monster that shared the rivers of what is now Niger with dinosaurs and, on the strength of a five-and-a-half-foot skull, may occasionally have eaten them. Forty feet. Even by that generous early estimate, Werner’s fifty-foot animal is the larger beast.

But the comparison has sharpened since. A 2019 reassessment pulled Sarcosuchus back to a more conservative maximum of about thirty-one feet — and the other contenders for largest-ever crocodilian, Deinosuchus and the giant caiman Purussaurus, cluster in the same thirty-three-to-forty-foot bracket, all of them reconstructed from fragmentary bone. In other words, the best-supported estimate for the largest crocodyliforms that ever lived now sits comfortably below what Werner claimed to have watched sunbathing on a sandbar. The Mahamba is not merely bigger than any living crocodile. It is bigger than the biggest crocodile the earth has ever produced a fossil of.

That should give even a sympathetic and optimistic reader pause.

The second stream

The easy move would be to file Werner under Victorian exaggeration and close the book. What complicates that is a second, entirely independent line of testimony arriving nearly a century later.

In the 1980s the biologist Roy Mackal travelled the Congo basin chasing Mokele-mbembe, the region’s more famous “living dinosaur.” Along the way he collected the vocabulary the Bobangi people used for the animals of their river, and it was more precise than an outsider might expect. There was the ordinary crocodile. There was the Nguma-monene, a long, ridge-backed thing that was something else again. And then there was the Mahamba: not a separate kind of animal but a crocodile in every way that matters — same shape, same habits — only monstrously, impossibly large, forty to fifty feet and more, said to lie up in long tunnels dug into the riverbanks. The people describing it were not confusing it with anything. They were insisting, from direct familiarity with the real crocodiles all around them, that this was one of those and simply far too big.

So we have two witnesses who never met, separated by a hundred years and by every difference of language, purpose and worldview, describing the same specific impossibility in the same specific water. That is a genuinely uncomfortable coincidence, and it is the strongest thing the Mahamba has going for it.

What could it be?

The serious hypothesis is a relic: a surviving or simply undescribed giant crocodilian, a lineage that kept the old Cretaceous dimensions going in the vastness of the Congo swamps where no one has ever managed a proper survey. It is not absurd on its face — the region is enormous, poorly mapped, and has surrendered new large vertebrates within living memory.

The less serious end of the shelf holds the idea, which surfaces now and then in the cryptid literature, that the Mahamba is no crocodile at all but some freshwater relative of the mosasaurs. A 1954 sighting in the Maika marshes is sometimes pressed into service here — a large reptile that reportedly lifted an abnormally long neck from the water before diving. But that long neck pulls in the opposite direction from everything else on record; it describes a different animal from Werner’s flat-backed, short-legged, unmistakably crocodilian giant, and folding the two together muddies rather than strengthens the case.

Then there is the explanation that requires nothing new at all. A single, genuinely enormous Nile crocodile — an old, exceptional individual pushing the upper limit of its kind — glimpsed across open water, with no fixed reference for scale and a rifle conspicuously absent, is exactly the raw material from which fifty-foot estimates are honestly made. Water flatters length. Distance deceives. Fear does the rest. Werner measured his monster against a steamer three hundred yards away, and even a careful man measuring by eye across that gap can be handsomely wrong.

I remember being on the banks of the Chobe River in Botswana, and just happening to look up. At some distance – my estimation was not dissimilar to Werner’s three hundred yard steamer – I saw what I thought was a large tree floating in the centre of the river. It took me a few moments to realised it was of course, a huge crocodile. The size really threw me off and at that distance, I almost certainly over estimated it. But I did think it was every inch of twenty feet, if not more. And I made the comparison to what was in front of me – a tour boat.

So, I have some sympathy for anyone matching boat sizes to unusually large crocodilians. But I think we can accept it’s not an exact science.

Where are the bones?

Sarcosuchus skull at the Museum d’Histoire Naturelle. No children were harmed in the taking of this photo 🙂

Which brings us to the question that closes the file on the Mahamba, as it closes the file on most of its kind.

We know Sarcosuchus was real because it left us a skull the length of a man and enough skeleton to argue over. We know the outer limits of crocodilian size because the fossil record, patchy as it is, has physically produced the animals. The Mahamba has produced witnesses — good ones, independent ones, a century apart — and not one confirmed bone. No skull, no skeleton, no shed tooth the size of a hand, nothing hauled from a bank or found bleaching on a sandbar. For an animal supposedly common enough that a working engineer saw several in the course of doing his job, that absence is very loud.

Sarcosuchus outgrew the living world and left us its remains. The Mahamba outgrew even Sarcosuchus, and left us only the water it disappeared into.

Monster Monday: The Nandi Bear

In the highlands of western Kenya, the land rises gently into long grass and scattered woodland. At dusk, the horizon softens. Shapes lose their edges. And in that space, between what is seen and what is assumed, something has been described for over a century.

Not a lion. Not a hyena. And not an ape. It’s not anything that fits comfortably into the known catalogue of African predators.

It has been called the Nandi Bear.

The name is misleading. There are no bears in Africa. In prehistory, the Atlas bear – a subspecies of the European brown bear, ranged from Morocco to Libya, but disappeared around 1,200 years ago. In sub-Saharan Africa, the only bear species to have ever been recorded was Agriotherium, which became extinct approximately two million years ago.

And yet, again and again, witnesses reached for that word, not because it was accurate, but because nothing else quite worked.

The Land and its People

The Nandi region is not wilderness in the romantic sense. It is lived-in land. Grazed, walked, and worked. Livestock are part of daily life, and with them comes a long, inherited awareness of predators.

In such landscapes, animals are not abstract. They are known through behaviour, through what they take, how they move, and what they leave behind.

Yet sometimes, something appears that does not behave or look as expected.

In Nandi accounts, this animal was described not just by its shape, but by its manner. It was said to move with a heavy, deliberate gait. To favour the head of its prey. To appear suddenly at the edges of habitation, then vanish just as quickly.

These are not the details of myth alone. They are the details of observation. Filtered through fear, yes, but clearly still rooted in experience.

What Is the Nandi Bear?

Descriptions of the Nandi Bear vary, but certain features repeat with striking consistency. The powerful, front-heavy build is something almost all witnesses have described. Similarly, the long, shaggy hair is inextricably linked to what we think of as the Nandi Bear.

Behaviour wise, a low, almost lumbering gait and a tendency towards being nocturnal all hint at something out-of-the-ordinary for the region.

It was also often said to attack livestock, and occasionally people, focusing on the head, and capable of crushing bone with immense force.

To European observers in the early 20th century, this was baffling. The closest comparison they could find was a bear. But what they were likely seeing, or trying to describe, was possibly something far more familiar, and yet somehow not quite right.

William Hichens and the East African Unknown

One of the most intriguing threads in the story of the Nandi Bear runs through William Hichens.

Hichens was not a passing observer. He lived and worked across Kenya and Tanzania in the early 20th century as a Colonial Administrator. Reporting accurately and subjectively was part of his everyday work, yet he took a sustained interest in reports of unusual animals. He is unusual in that he did not limit himself to a single mystery.

He investigated numerous animals now known as cryptids, and was said to have encountered three during his time in Kenya and Tanzania. These include the Agogwe (a so far undiscovered potential hominid not unlike the Orang Pendek – think in terms of a small Bigfoot), the Mngwa (a mystery big cat), and the Nandi Bear.

Of these, the Nandi Bear and the Mngwa share a particularly interesting overlap.

The Mngwa, the Nunda, and a Shared Language of Fear

Further south, in Tanzania, reports emerged of another animal: the Mngwa.

Described as a large, elusive, cat-like predator, the Mngwa was associated with sudden, violent attacks and a reputation that extended beyond any known species. Like the Nandi Bear, it existed in that uneasy space between recognition and uncertainty.

It was also known by another name: Nunda (or Nunda).

Translated loosely, this has been interpreted as meaning “fierce animal.”

The linguistic overlap is striking. Not because it proves the two creatures are the same but because it suggests a shared framework. A way of describing something dangerous that does not need to be taxonomically precise.

Hichens moved through both regions. He heard these accounts not as isolated stories, but as part of a broader pattern – a recurring idea of an animal that sits just outside the known.

During his time, Hichens also wrote articles on ‘lion men’, ‘lizard men’, and even a book on Africa’s mystery beasts. In context, he also wrote about the cultural tribal dances and their meanings, and the behaviour of leopards. Despite the sensationalism of some of his subjects, his approach was broad and open-minded in all cases.

Furthermore, the Nandi Bear is known as Chemosit by the Kalenjin of the Rift Valley, although some argue this is a slightly different animal. The same goes for the more baboon-like Koddoelo of the Pokomo people, and the Shivuverre – also from Kalenjin folklore, the Mubende Beast, and Nyangau (Swahili), all of which at some time have come under the broad description of the Nandi Bear.

Sightings, Patterns, and Silence

Accounts of the Nandi Bear persisted through the early and mid-20th century. Colonial records, settler reports, and local testimony all contributed to a body of descriptions that, while varied, retained a core consistency.

And then, gradually, they stopped. The last widely cited sighting dates to 1998. Since then, there has been silence.

This absence is often treated as evidence against the animal’s existence. But it can also be read another way. If something did exist, something rare, elusive, and already under pressure from expanding human presence, its disappearance would not be surprising.

Unfortunately, in this day and age, its extinction would be all but guaranteed.

Explanations: Known Animals, Unknown Edges

The Nandi Bear sits at an intersection where explanation becomes interpretation.

The Hyena Hypothesis

The most widely accepted explanation is the spotted hyena. Its sloping back, powerful jaws, and bone-crushing behaviour align closely with many of the descriptions.

And yet, there are discrepancies. The size. The posture. The sense, repeated in multiple accounts, that this was something heavier, more deliberate.

I’m also loathe to believe that those living among the animals of the region would make this mistake. The spotted hyena is well known, and locally called Fisi.

That said, I have seen for myself how local people can be isolated from the wildlife around them. Poverty and lifestyle can mean they simply don’t encounter them every day. But still, taking this to the point of such a major misidentification is hard to believe.

A Larger Hyena, Out of Time

Here, the thinking of Bernard Heuvelmans becomes relevant.

Heuvelmans proposed that some cryptid reports may reflect relict populations of animals thought to be extinct. In this case, that has led to speculation about larger, prehistoric hyena species surviving longer than expected in isolated regions.

There is no direct evidence for this. But the idea persists because it offers a middle ground: not myth, not fantasy, but something biologically plausible that has simply slipped through the net of formal recognition.

A similar argument could be made for the likes of Agriotherium. Agriotherium was a large, heavy-built carnivore that is considered to be the only bear to have ever colonised sub-Saharan Africa. Its fossil remains have been found throughout South Africa and Ethiopia, dating from 11 million years ago to just two million years.

Misidentification and Memory

Equally, the Nandi Bear may be an accumulation of misidentified encounters with hyenas seen under poor conditions, their features exaggerated by fear and retelling.

But this does not diminish the phenomenon. It explains how it forms, in some cases. But not necessarily all.

Why the Nandi Bear Remains

What is striking is not just that the Nandi Bear was reported but how consistently it was described, across time and by different witnesses who had no reason to align their stories.

And what is perhaps more striking still is how quietly it has faded.

No dramatic conclusion. No definitive identification. Just a gradual absence.

In that way, it resembles many of the animals that sit at the edge of human awareness. Occasionally seen, never fully understood, and eventually, perhaps, gone.

The Animal We Don’t Quite See

The Nandi Bear may never have been a single, identifiable species.

It may have been a hyena, seen differently. A memory, shaped collectively. Or, as Bernard Heuvelmans might suggest, the last trace of something that once moved more widely across the landscape.

But whatever its origin, it tells us something consistent.

That even in places we think we understand, the places mapped, named, and studied, there still remain gaps. Not just in knowledge, but in interpretation.

And sometimes, those gaps take on a formidable shape. Not fully seen. Not fully known. But still, waiting in the darkness for us to remember.

It’s an idea I’ve returned to often in my own writing—particularly in The Daughters of the Darkness, where the boundary between predator and myth can feel especially thin. Landscapes like these don’t just hold animals. They hold memory, interpretation, and the quiet suggestion that something may once have moved there that no longer does.

Or perhaps still does, just beyond the edge of certainty.

Man-Eater Monday: The Sankebetsu Brown Bear Incident

In the winter of 1915, the settlement of Sankebetsu, in northern Japan, was already under strain.

Snow lay deep across Hokkaido. Food stores were thin. Travel was difficult, sometimes impossible. For the people living at the margins of cultivated land, winter was not simply a season — it was a test of endurance.

What went largely unconsidered was that the same conditions applied to everything beyond the settlement’s boundaries.

The forests were locked in ice. Natural forage was scarce. Prey animals were weakened, dispersed, or absent altogether. The winter that pressed hardest on human communities was doing the same to the wildlife around them. But at the time, this was not a connection people were trained to make.

Ecology, as a way of thinking, had not yet entered the conversation. Hardship was viewed as a human problem, unfolding against a largely static natural backdrop. The idea that animals might also be responding — adapting, learning, and changing behaviour under pressure, was rarely entertained.

It was in this context that the Sankebetsu incident began.

A first encounter and a dangerous assumption

The bear’s first appearance was not dramatic in scale, but it was decisive in consequence. In December 1915, a large brown bear entered the settlement and attacked a woman working near her home. The encounter was sudden and close-quarters. She was killed before any effective intervention could be made.

The bear did not linger. After the attack, it retreated back into the surrounding forest.

That withdrawal shaped how the incident was understood.

Within the settlement, the prevailing belief was that the animal had been startled — that the violence was reactive, not intentional, and that the danger had passed with the bear’s departure. The incident was treated as an isolated tragedy rather than the opening stage of a larger threat.

No co-ordinated hunt followed. No sustained effort was made to track the animal’s movements or assess whether it might return.

This response was not careless so much as culturally conditioned. At the time, apex predators were often viewed as opportunistic but fundamentally avoidant of humans. An animal that fled was assumed to have learned fear.

But this assumption rested on a misunderstanding of how predators learn.

An animal that kills and escapes unharmed has not seen that behaviour punished. It has been reinforced. The boundary between human and prey does not harden, it weakens.

In retrospect, the bear’s retreat was not a conclusion. It was a pause.

Escalation isn’t chaos, it’s pattern

When the bear returned, it did not behave erratically.

It came back into the settlement repeatedly, moving with increasing confidence through spaces that had already been shaped by human presence. Homes were entered. People were taken from places that should have been safe.

One of the most disturbing moments came shortly after the initial attack, when the bear returned during a funeral held for the first victim. Drawn by human activity and the presence of food, it entered the area and killed mourners gathered there.

The violence was no longer confined to a single encounter. Over the course of one night, multiple people were killed in separate attacks. By the time the bear was finally stopped, five lives had been lost, several of them within hours of one another.

What is striking, in retrospect, is not the scale of the violence, but its consistency.

The bear did not flee after these encounters. It did not act randomly. It returned to the same settlement, exploited moments of vulnerability, and withdrew only when challenged. Each successful attack reinforced the same lesson: humans were accessible, and resistance was minimal.

This is the point at which many retellings introduce the language of madness or bloodlust. But escalation, in cases like this, is rarely chaotic. It is patterned.

Under conditions of prolonged scarcity, the bear’s behaviour reflected learning rather than frenzy. What appeared to the community as senseless violence followed a grim internal logic shaped by hunger, opportunity, and success.

Human hesitation, and a belated resolution

As fear spread through the settlement, so did uncertainty.

There was disagreement over whether the same bear was responsible for each attack. Some believed the animal would eventually move on. Others feared that a co-ordinated response might provoke further violence. Time was lost to debate, hesitation, and the difficulty of acting decisively in extreme winter conditions.

When a concerted effort was finally made to track the bear, it revealed just how unprepared the community was for such a task. Weather obscured trails. Knowledge of bear behaviour was inconsistent, drawn from folklore, fragments of experience, and assumption rather than strategy.

Eventually, a group of hunters succeeded in locating and killing the animal. The bear was identified as a large male brown bear, in poor physical condition. Its body showed signs consistent with prolonged scarcity. With its death, the attacks stopped.

The immediate danger to Sankebetsu was over.

But the resolution came only after multiple lives had been lost, and only once the cost of inaction had become undeniable. The bear’s death did not mark the defeat of a monster, but the delayed recognition of a threat that had been misunderstood from the outset.

Then, and now

More than a century after the Sankebetsu incident, it is tempting to look for repetition — to imagine the same landscape quietly replaying its past.

That is not what the evidence suggests.

Brown bears still inhabit Hokkaido today. The species persists across much of the island’s forests and mountain ranges, and in some areas populations are thought to be stable or recovering after decades of decline. The region where Sankebetsu once stood is no longer a permanent settlement, and there is no indication that it has become a modern centre for serious bear attacks.

History, in this sense, is not repeating itself geographically.

What has changed is the broader context in which people and bears now coexist.

In 2025, Japan recorded 13 human fatalities and more than 100 injuries resulting from bear encounters, involving both Asiatic brown bears and Asiatic black bears. These incidents were spread across multiple prefectures and environments — from rural settlements to the edges of towns — rather than concentrated in any single location.

The pressures behind them are familiar: reduced natural food availability, changing land use, and expanding human presence in areas once less frequently occupied. Bears range more widely when resources are scarce, and humans now occupy landscapes that were once seasonal or marginal.

The relevance of Sankebetsu, then, is not that it is happening again in the same place. It is that the same ecological forces – scarcity, overlap, and hesitation, all continue to shape encounters between people and large predators, wherever clear boundaries erode.

The quieter truth of man-eater stories

The Sankebetsu bear was not a creature of myth, nor a symbol of evil. It was an animal responding to scarcity, learning from success, and moving through a landscape that no longer offered clear separation between forest and home.

Man-eater stories endure not because they reveal something monstrous about animals, but because they expose a recurring human blind spot: the tendency to see nature as static, until it reacts.

When prey disappears, boundaries blur. When boundaries blur, conflict follows.

The question is not whether such stories will happen again, but whether we recognise the conditions early enough to change the outcome.
