What are 4 unique things about killer whales?

One interesting thing I have found is that there is a whale that has the exact same killer whale fin. It can easily be mistakin for a killer whale when really it is just the false killer whale. The false killer whale is exactly a dolphin!Status: Endangered in Oregon, Washington, and California. Killer Whales are also called orcas but you probably already knew that. Killer Whales love playing! sorry i cant remember any more!
