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.
Species: California sea lion, Zalophus californianus
