What do Whales do?

Whales are not the only mammals that live in the sea. You also have the more hairy kind of sea mammal, like sea lions, seals and walruses. They catch fish in the sea, but spend a lot of time on land, mating and having babies, or simply sunbathing!

Whales like to lie down next to each other on the rocks or sand and take a nap, especially after eating, when their bellies are full.
