Killer whales are found in all oceans in the world, usually preferring to live at depths of 20 to 60 meters (65 to 195 feet). They are most abundant in colder waters like Alaska, Norway, and Antarctica but can also be found in tropical and subtropical oceans. Killer whales tend to stay in their general home range year round, they do not migrate due to the weather. There are two types of killer whales, Transient and Coastal. Transient killer whales tend to stay away from the shoreline, they are not, however, completely offshore. Coastal killer whales tend to stick to coastal regions.
The diet of an Orcinus Orca eat a very wide variety of large prey that includes seals, squid, sea lions, smaller whales and dolphins, fish, sharks, octopi, sea turtles, river otters, and other animals. Killer whales eat an average of about 45 kilograms (99 pounds) a day but they can eat much more than that. When eating larger prey, killer whales tend to tear their prey apart before eating. Whales hunt in groups called pods, they use coordinated social behavior and communication to hunt prey.
