Orcas (also called killer whales) are the largest dolphins in the world. They are called 'whales' because of their size. Males typically range from 6 to 8 meters long and weigh in excess of 6 tons. Females are smaller, generally ranging from 5 to 7meters and weighing about 3 to 4 tons.Orcas have mostly black skin with white patches.They are found in all the world's oceans, from the cold of the Arctic to the tropical seas. They are really easy to identify because of their white and black coloring.

     Orcas feed on fish, squid, birds, and marine mammals. In the wild, orcas live from 30 – 50 years. However, pollution and chemical waste make orcas more likely to get diseases so the Orca population is getting smaller.
