There are no estimates of global abundance for D. capensis and few local abundance estimates. Off California, USA, at the northern part of this species' range, abundance estimates have ranged from about 11,000 to 49,000, averaging about 22,000 (CV = 50%) dolphins between 1999 and 2005 (Barlow and Forney, in press). Dolphins found off California are part of a larger population extending southward through Mexico, where Gerrodette and Palacios (1996) estimated 55,000 within Pacific coast waters of the Mexican EEZ and 69,000 in the Gulf of California. One relatively well-studied variant of the long-beaked form is the Baja neritic race, which is found in the Gulf of California (Sea of Cortez), Mexico, and the coastal warm-temperate eastern North Pacific, north of 20Â°N. About 15,000-20,000 are estimated to occur off South Africa (Cockcroft and Peddemors 1990). The tropicalis subspecies is widespread in the Indian and western Pacific oceans, but there are no estimates of abundance for any portion of its range.
