Orcas

Do you know that dolphins and Orcas are in the same family? Like all whales, Orcas are mammals. They hunt everything from fish to sea lions, penguins, sea turtles, sharks, and even other kinds of whales. They usually eat 225 kilograms of food every day. They never eat seaweed. People often call Orcas as 'wolves of the sea'. They always work together as they hunt. Sometimes, a group of whales join forces to attack a very big animal, such as a blue whale.
