California sea lions are known for their intelligence, playfulness, and noisy barking. Their color ranges from chocolate brown in males to a lighter, golden brown in females. They are members of the eared seals. They have external ear flaps and large flippers that they use to "walk" on land. In the ocean, they use their long front flippers to swim.  California sea lions are our most common patient at PMMC.  


California sea lions are found from Vancouver Island, British Columbia to the southern tip of Baja California in Mexico. You can also find them congregating on rocky areas, jetties, buoys off the coastline.

 California sea lions are opportunistic eaters, feeding on squid, octopus, hake, Pacific whiting, sardines, jack, herring, rockfish, mackerel, and small sharks.
