Just beyond the Golden Gate lies Greater Farallones National Marine Sanctuary and Cordell Bank National Marine Sanctuary. These Sanctuaries encompass more than 4,000 square miles of federally protected open ocean and coastal waters off the North-Central California coast and one of the most productive and biodiverse ocean ecosystems on the planet. These waters are home to one of the largest feeding grounds for white sharks, 29 species of whales and dolphins, over 390 species of fish, and over 330 species of invertebrates including deep-sea corals, sponges, shrimp, crabs, octopuses, and more!
