California Sea Lions have external ear flaps. Sexual dimorphism is present in this species where adult males are much larger with a sagittal crest. These animals can be any color from tawny brown to black. California Sea Lions are able to rotate their hind flippers and walk on all fours, which makes them different from Phocids. They can dive to depths of 270m and hold their breath for around 10 minutes if needed. Sea lions are very intelligent and excellent predators.
