The Atlantic humpback dolphin is a dolphin species that is found on the west coastal areas of Africa. Unfortunately the IUCN classes it as critically endangered. Apart from their difference in range with the Indo-Pacific dolphin, they are also different in appearance, particularly colouring.
It is found along the coast from the Sahara to Angola, generally in water less than 20m deep. It is generally shy, does not ride the bow wave of boats and ariel jumps are pretty rare. Usually found in groups of 1-8, occasionally they have been seen in groups of 20-40.
Generally they look for food in the shallows, and occasionally right in the surf. They have been known to engage in cooperative fishing methods with Mauritanian Imraguen fishermen. They do this by driving the fish towards the shore and into the nets. They favour inshore fish such as mullet.
As in many other parts of the world, and other dolphin species, one of the biggest threats they face is incidental capture in gill nets.
It is considered critically endangered, partly because it has been shown to be damaged by coastal development, and this is increasingly common in its range.
