High Quality Content by WIKIPEDIA articles! The killer whales of Eden, Australia were a group of killer whales (Orcinus orca) known for their co-operation with human hunters of other whale species. They were seen near the port of Eden in southeastern Australia between 1840 and 1930. A pod of killer whales, which included amongst its members a distinctive male called Old Tom, would assist whalers in hunting baleen whales. The killer whales would find target whales, shepherd them into Twofold Bay, and then alert the whalers to their presence and often help to kill the whales.
