Orca

The orca, or killer whale can be found in the Arctic and Antarctic regions of the world. They are the fiercest whales and they eat fish, squid, birds, seals, and even other whales. They hunt in groups and share food with each other. Whales have to come to the surface of the water to breathe. Orca whales live in family groups called "pods".. Special fact: Like other toothed whales, orcas can "talk" to each other by making clicks, screeches, and whistles under water.
