Red Triangle (Pacific Ocean)

The Red Triangle is the colloquial name of a roughly triangle-shaped region off the coast of northern California, extending from Bodega Bay, north of San Francisco, out slightly beyond the Farallon Islands, and down to the Big Sur region, south of Monterey. The area has a very large population of marine mammals, such as elephant seals, harbor seals, sea otters and sea lions, which are favored prey of great white sharks.
