Five species of Fur seals exist. The most familiar one is known as the California sea lion. Fur seals live in the Northern Hemisphere and are referred to as eared seals due to the fact that their ears are very small. They are expert swimmers and divers, thus Fur seals have acute vision and good hearing underwater. They catch fish under water, and they breed on the beach colonies.
Fur seals are gregarious.
Usually during the breeding season, dominant males fast. Females are pregnant up to one year and usually give birth to one pup. They young remain with the mother until it can defend itself. Males are much larger than the females. They can be trained to perform simple tricks.
