Polar Bear Sleeping

Most polar bears sleep for seven to eight hours at a stretch and they take naps, too. In that way, they’re a lot like people.
Polar bears nap just about anywhere and any time, and especially after feeding on a seal. Napping helps them conserve energy. A polar bear's entire existence centers on hunting and conserving energy.

Sunk Hippo

The word "hippopotamus" derives from the ancient Greek words hippos(horse) and potamos(river), meaning "horse of the river". Hippos spend most of their days wallowing in the water or the mud, with the other members of their pod. The process of surfacing and breathing is automatic, and even a hippo sleeping underwater will rise and breathe without waking.
