Old Tom's role was commonly to alert the human whalers to the presence of a baleen whale in the bay by breaching or tailslapping at the mouth of the Kiah River, which is one of the smallest rivers, where the Davidson family had their tiny cottages. This role endeared him to the whalers and led to the idea that he was "leader of the pack," although such a role was more likely taken by a little known female (as is typical among killer whales). while the killer whales ate the tongue and lips of the whale, then haul it ashore. The arrangement is a rare example of
mutualism between humans and killer whales. The arrangement was called "the law of the tongue". The killer whales would also feed on the many fish and birds that would show up to pick at the smaller scraps and runoff from the fishing. Many of the Eden killer whales were individually known and named, often after Yuin whalers who had died. Some of best known killer whales included Tom (who died 15 September 1930), Hooky, Humpy (died 1926/7), Cooper, Typee (died 1901), Jackson, Stranger, Big Ben, Young Ben, Kinscher (female), Jimmy, Sharkey, Charlie Adgery, Brierly, Albert, Youngster, Walker, Flukey, Big Jack, Little Jack, Skinner, and Montague. The probable structure and history of the pod during this period was reconstructed by zoologist
Danielle Clode. == End of whaling arrangement ==
