stock here, there is a lot of documentaries on YouTube on Killer whales. But this story is amazing.
============
The book is Killers of Eden by Tom Mead, originally published in 1961. Mead was a Sydney journalist. His account describes a roughly century-long tradition at Twofold Bay in which wild orcas cooperated with shore-based whalers hunting humpback and southern right whales. The phenomenon is unusually well documented: journals, newspaper accounts, photographs, and even early motion-picture footage survive or are referenced in the historical record. Dolphin Books
The biggest correction is the family name. The famous whaling family was the Davidson family, not Robinson. Three generations of Davidsons worked with the orcas. George “Fearless” Davidson became the best-known member of the family during Old Tom’s era. Dolphin Books
What actually happened
The basic hunting sequence in your account matches the documentary evidence surprisingly closely.
The orcas would locate migrating baleen whales and either herd them toward Twofold Bay or alert the shore whalers. Historical accounts say they did this with conspicuous splashing and tail-slapping near the whaling station, sometimes at night. The men then launched approximately 9-meter open whaleboats and followed the orcas. PubMed Central (PMC)
Once the hunt was underway, different orcas apparently performed different functions. Some harassed and herded the whale, some attacked the fins and flukes, some bit around the lips and head, and others reportedly breached over the whale or interfered with its breathing. The exhausted whale was ultimately harpooned and killed by the human crew. PubMed Central (PMC)
That is genuine cooperative hunting between two species, not merely orcas scavenging from human kills. Modern researchers characterize the relationship as mutualistic because both sides apparently gained something they would otherwise have had to expend substantially more effort obtaining. PubMed Central (PMC)
“Law of the Tongue”
This part is particularly well supported.
Once a whale had been killed, the whalers anchored or buoyed the carcass and left it for roughly 24–48 hours. The orcas preferentially ate the whale’s tongue and lips, after which the humans returned and processed the remaining carcass for blubber and oil.
That arrangement became known as the “Law of the Tongue.” PubMed Central (PMC)
There is a fascinating biological wrinkle: modern researchers point out that killer whales elsewhere also preferentially consume whale tongues because they are exceptionally rich tissue. So the arrangement may have worked perfectly because the orcas strongly valued something the whalers didn’t particularly need. PubMed Central (PMC)
That is about as elegant a natural division of resources as you could imagine.
Did Old Tom actually tow the boats?
There are historical accounts saying yes, but this is one of the details where I’d distinguish documented testimony from physical proof.
Accounts describe Old Tom grabbing a tow rope at the beginning of a chase and also taking a harpoon line in his mouth after the whale had been struck, apparently helping slow the whale. The 2023 scientific paper specifically discusses those reports. PubMed Central (PMC)
Old Tom’s surviving teeth exhibit conspicuous wear, and this has traditionally been attributed to repeatedly gripping ropes.
But modern researchers are cautious: the tooth wear is consistent with rope work but is not forensic proof of it. Other feeding stresses could produce some of the same wear. PubMed Central (PMC)
So I’d phrase that part:
Contemporary accounts say Old Tom sometimes took tow or harpoon lines in his mouth; the unusual wear on his teeth is consistent with those stories, although scientists cannot prove that rope pulling caused the wear.
That’s stronger historically than saying the grooves definitively prove towing.
The overboard-whaler rescues
Stories of the orcas protecting whalers and helping men in the water occur repeatedly in Eden oral histories. They fit a much larger body of testimony describing unusually tolerant interaction between the animals and humans.
But these individual rescue episodes are inherently harder to establish to the same standard as the cooperative hunting itself. There aren’t instrumented observations, obviously. They should therefore be described as contemporary or local eyewitness accounts, rather than experimentally established animal behavior.
There is nevertheless extraordinary testimony about how accustomed the animals were to humans. Thaua oral history records people swimming alongside the orcas and holding their dorsal fins, without injury. PubMed Central (PMC)
And there’s a deeper story Mead didn’t fully have
This is perhaps the most interesting thing I found.
The Davidson-orca partnership apparently didn’t originate with European whalers.
The local Thaua people of the Yuin nation had a much older cultural and hunting relationship with the Twofold Bay killer whales. Thaua oral tradition describes cooperative hunting and sharing whale carcasses with orcas long before commercial European whaling began.
The 2023 peer-reviewed study concludes that European commercial whaling beginning around 1828 appears to have adopted an existing Indigenous human-orca relationship. Indigenous whalers subsequently made up an important part of European whaling crews because of their skill and knowledge. PubMed Central (PMC)
Researchers believe the arrangement may therefore have existed for far longer than the Davidson family’s several generations.
That changes the story from:
“A whaling family somehow befriended killer whales.”
to something more interesting:
“Humans and a local population of killer whales developed a hunting culture together, possibly over many generations, and European settlers later participated in it.”
Old Tom really is still there
Old Tom died in September 1930, and his skeleton is preserved at the Eden Killer Whale Museum. By then most of the cooperative orcas had disappeared from the area. Commercial processing of baleen whales at Eden had essentially ceased by 1928. PubMed Central (PMC)
The traditional story is that Old Tom was extremely old—sometimes estimates of 80 or 90 years were given—but his actual age remains disputed. Modern researchers specifically caution that both his age and the exact social organization of the Eden orcas are uncertain. PubMed Central (PMC)
There’s even DNA evidence now
Scientists actually sampled Old Tom’s museum remains and sequenced his genome.
The 2023 research found that his genetic lineage is unusual and that they could not identify a clear direct descendant among the modern killer whales sampled around Australia and New Zealand. That lends weight to the possibility that the distinctive Eden group disappeared rather than simply continuing unchanged somewhere nearby. PubMed Central (PMC)
So the phenomenon wasn’t just a colorful 19th-century newspaper yarn. We now have the animal’s skeleton, photographs, historic records, Indigenous oral history, early film documentation, and Old Tom’s DNA.
One more correction to the version you pasted: the cooperation wasn’t just with humpbacks. The record explicitly includes humpback whales and southern right whales, among other baleen whales. PubMed Central (PMC)
The result is one of the strangest well-documented human–wild animal partnerships I know of: wild apex predators voluntarily signaling humans, coordinating a hunt with them, apparently recognizing individual boats and people, and then dividing the carcass according to a stable resource-sharing system.
The 1961 book was an important part of preserving the Eden story before many of the people who remembered the old whaling period were gone.
