This face belongs to a sea otter. It spends nearly its whole life at sea, barely touching land.

Sea otters sleep floating on the water. The problem is the waves. While they sleep, waves can carry a friend far away.

With no friend to hold, they wrap kelp around their bodies. Kelp is a long seaweed rooted on the seafloor, so it holds them like an anchor.

A group of otters floating together like this is called a raft in English. Yes, a raft.

Pups sleep on their mother's belly. A pup's fur is so full of air that it can't dive even if it wants to. It just bobs along.

One more thing. Under each arm, a sea otter has a loose pocket of skin. They keep food and a favorite rock in it. They use that rock to crack open clams on their belly.

Watch it as a short
