Old Tom (c. 1895 – 17 September 1930) was the name given to an orca by whalers in the port of Eden on the southeast coast of Australia. Old Tom measured 22 feet and weighed 6 tons. The skull measured 1.02 meters and the teeth measured about 5.31 inches. Old Tom was thought to be the leader of a pod of killer whales who helped the whalers by herding baleen whales into Twofold Bay. The killer whales would help kill the whales; in return, the whalers allowed the killer whales to eat the tongues and the lips of the baleen whales, an agreement known as the Law of the Tongue.
On 17 September 1930, Old Tom was found dead in Twofold Bay. Before his death Old Tom had been thought to be over 80 years old,
