Orcas are mammals found in all the world’s oceans.
Orcas are also known as killer whales. They live in groups called pods. The pods travel and hunt together. Orcas have developed many different ways of hunting. They throw themselves onto beaches to chase sea lions in shallow water. They also tip over ice floes to knock seal and penguins into water.
Like all mammals, orcas breathe air. They must come to the surface to breathe.
