Atlantic humpback dolphin

The Atlantic humpback dolphin (Sousa teuszii) lives in shallow coastal and estuarine waters of West Africa, ranging from Western Sahara to Angola and generally staying in water less than about 20 meters deep. It is a robust dolphin with a well defined beak, gray or white coloring and a distinctive hump beneath the dorsal fin; newborns weigh about 14 kilograms and measure roughly 100 centimeters, while adult males can reach about 2.8 meters and 280 kilograms. It feeds mainly on inshore schooling fish such as mullet, supplemented by other coastal fish and crustaceans depending on location, and is classified as Critically Endangered by the IUCN, threatened by entanglement in gill nets, habitat loss, overfishing, pollution and climate change.
