Orca, the killer whale Revered king of the oceans, orca has no fear and will eat anything, even moose and other whales. They have attacked and killed great white sharks. There are, however, no documented attacks on humans, although trainers have been killed by orca in captivity. There are many myths and legends about orca in Northwest Native culture. They have no natural predators.
Orcas live in family units called pods.
They usually remain with their specific pod for life. Resident pods are usually much larger, often seen in groups called superpods, which may have 150 members. Transient pods are normally seen in groups of five to 10 animals. They may be seen in one area for a month, then disappear for several weeks.
