The California sea lion is a type of seal that lives in cool waters off the rocky coast of western North America. Breeding areas are called rookeries.
Males also have a thick furry mane around the neck.
The nostrils are closed in the resting state. The sea lion has small external ears and a good sense of hearing. It also has keen eyesight but no color vision. Seals don't chew their food. They swallow it in large chunks.
