Parasitic zoanthid anemones cover, encrust and overwhelm a golden gorgonian. The gorgonian on the left has been completely parasitized by zoanthid anemones, while the gorgonian to the right remains free of zoanthids (for now). A garibaldi swims below the two sea fans. The golden gorgonian is a filter-feeding temperate colonial species that lives on the rocky bottom at depths between 50 to 200 feet deep. Each individual polyp is a distinct animal, together they secrete calcium that forms the structure of the colony. Gorgonians are oriented at right angles to prevailing water currents to capture plankton drifting by.

Red gorgonian on rocky reef, below kelp forest, underwater. The red gorgonian is a filter-feeding temperate colonial species that lives on the rocky bottom at depths between 50 to 200 feet deep. Gorgonians are typically oriented at right angles to prevailing water currents to capture plankton drifting by.

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
Location: Coronado Islands (Islas Coronado), Baja California, Mexico

Two Giant Black Sea Bass in a Courtship Posture, in Kelp at Catalina Island. In summer months, black seabass gather in kelp forests in California to form mating aggregations. Courtship behaviors include circling of pairs of giant sea bass, production of booming sounds by presumed males, and nudging of females by males in what is though to be an effort to encourage spawning.
Species: Giant black sea bass, Stereolepis gigas
