Killer Whales
They are also called Orcas.
They are mammals like we are. They are the largest of all dolphins.
They can grow to be 28 feet long and weigh 12 thousand pounds. But the largest killer whale ever was 32 feet long and weighed 22 thousand pounds.
A baby orca is called a calf. When the calf is born, he weighs 400 pounds. They can live as long as 90 years!
They usually swim 3 to 4 miles an hour, but they can swim up to 45 miles per hour.
They live in every ocean in the world.
They can eat 500 pounds of food every day.
What do you think they eat? Name a couple of underwater animals.
They eat fish, squid, penguins, seals, sea lions, dolphins and walruses. They are at the top of the food chain.
Killer whales have 45 teeth and each one is about three inches long.
They have a blowhole. They have to come up to the surface of the water to breathe.
They are black and white because it helps camouflage them in the water. Animals have a hard time seeing them.
Killer whales live in pods. Pods are like families. Most pods are led by females. They travel and hunt together in their pod.
Some killer whales are famous. One was in a movie called Free Willie. You can also see them at Sea World.
