Killer whales are present in Gulf of Guinea waters although population size is not considered in great numbers. A killer whale was harpooned some 15-20 nm south of Abidjan in 1958 but the animal sank. This shows that killer whales are present in the West African marine waters. Observers on industrial tuna purse-seiners reported a few sightings off the coast of Liberia, Ivory Coast and Ghana.
