The way otters eat sea urchins is by swimming to the bottom of the ocean. Then they get a rock and swim to the top with it and crack open the sea urchin on the stone. Sea Otters do not migrate. The rest of their time is spent playing. Playing helps Otters with their life long skills.
Otters really like to play.
River Otters have been known to bite a beaver's tail and then run away. A mud slide or a snowy hill is like a play ground for Otters. Otters will also take over a beaver's dam so she can have pups. Doing this project really helped me with my computer skills. Now I can tell my stuffed toy Otter what he should do and eat while I am at school.
