Skeleton of Old Tom in the Eden Killer Whale Museum

Old Tom (c. 1895 – 17 September 1930) was a killer whale (orca) known to whalers in the port of Eden on the southeast coast of Australia. Old Tom measured 22 feet (6.7 m) and weighed 6 tons, with a 1.02 m skull and teeth about 5.31 inches (13.4 cm) long. Old Tom was thought to be the leader of a pod of killer whales which helped the whalers by herding baleen whales into Twofold Bay.[1] The whalers then allowed the killer whales to eat the tongues and lips as their share of the kill, a practice known as the "Law of the Tongue".

On 17 September 1930, Old Tom was found dead in Twofold Bay. Before his death, he had been thought to be over 90 years old.[2] Examination of his teeth indicated he died around age 35,[3] but this method of age determination is now believed to be inaccurate for older animals.[4]

Old Tom's bones were preserved and his skeleton is now on display in the Eden Killer Whale Museum.[5]
