California Sea Lion

California sea lions color ranges from chocolate brown in males to a lighter, golden brown in females. Males reach 850 pounds (390 kg) and seven feet (2.1 m) in length. Females grow to 220 pounds (110 kg) and up to six feet (1.8 m) in length. They have a "dog-like" face, and at around five years of age, males develop a bony bump on top of their skull called a sagittal crest. The top of a male's head often gets lighter in color with age. These members of the otariid or walking seal family have external ear flaps and large flippers that they use to "walk" on land.
