Huge California Sea Lion Male Underwater, a bull, patrolling his breeding harem and territory, Coronado Islands, Mexico. His sagittal crest, the bony bump on his head that distinguishes adult male sea lions, is clearly seen. This particular sea lion bears an orange tag on his left foreflipper, probably as a result of rescue and release as a young sea lion years earlier.
Species: California sea lion, Zalophus californianus

Pacific Harbor Seal Pup in La Jolla About Three Weeks Old, hauled out on a white sand beach along the coast of San Diego. This young seal will be weaned off its mothers milk and care when it is about four to six weeks old, and before that time it must learn how to forage for food on its own, a very difficult time for a young seal.
