Large Adult Male California Sea Lion Bull Underwater, Mexico. His sagittal crest, the prominent bump on the top of his head, is clearly seen. A few bubbles trail behind him because he typically barks underwater as he swims. This bull had assembled a large group of adult females and remained in a 75-yard stretch of rocky shoreline to guard them from other males. Here he is seen patrolling the underwater perimeter of his harem territory, something he does often.

Inquisitive young California sea lion underwater inspects my glove by gently mouthing it. This is a pup-of-the-year born in June and only about five months old. Sea lions are tactile creatures and learn about objects and their surroundings by biting on them. Coronado Islands near San Diego, Baja California, Mexico.
