Ta. Jefferson et al., DOLPHINS AND PORPOISES OF WEST-AFRICA - A REVIEW OF RECORDS (CETACEA,DELPHINIDAE, PHOCOENIDAE), Mammalia, 61(1), 1997, pp. 87-108
A review indicates that nineteen species of dolphins and porpoises (ce
tacean families Delphinidae and Phocoenidae) occur in West African wat
ers (from the Strait of Gibraltar to the Congo River). In addition, tw
o other cold temperate species reach their southern limit at the north
ern border of the area. For each species, distribution records in West
African waters are reviewed. A key to dolphins and porpoises of West
Africa, based on external appearance, is presented to aid in identific
ation.
