Range Description
Pacific white-sided dolphins inhabit temperate waters of the North Pacific and some adjacent seas (Sea of Japan, southern Okhotsk Sea, the southern Bering Sea and southern Gulf of California) (Brownell et al. 1999; Van Waerebeek and Würsig 2002). Their range includes continental slope waters of the Western North Pacific as far south as southern China, shelf and slope waters of the eastern North Pacific from the Gulf of Alaska southward to Baja California, Mexico, and deep offshore waters of the North Pacific between about 35˚N and 47˚N latitude (Hobbs and Jones 1993).
