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.

Isla San Pedro Martir at sunset with extensive forest of Cardon Cactus seen on the summit ridge of the island, aerial photo, Sea of Cortez, Mexico. San Pedro Martir Island and its marine life are, since 2002, part of the San Pedro Martir Biosphere Reserve, and is regarded as a natural laboratory of adaptive evolution, similar to that of the Galapagos Islands. It is home to 292 species of fauna and flora (both land-based and aquatic), with 42 species protected by Mexican law, and 30 listed on the Red List of Threatened Species. San Pedro Martir is also unique in the area for its year-round quantity of birds. The island is the only island in the area with a perpetually swirling cloud of sea birds. This is because the water around the island, has some of the most successful marine productivity in the world.
