Find out more about the ecology, distribution, abundance and conservation status of this Critically Endangered species, and the threats that are causing its decline.

Interactive Map

Atlantic humpback dolphins are only found in the nearshore waters of the tropical and subtropical Atlantic coast of Africa.  Sightings, strandings and bycatch records confirm the species’ current or recent presence in 13 countries between Western Sahara in the north and Angola in the south. A lack of records from the remaining six countries within that range could be the result of the very limited research that has taken place in the region to date, or reflect a genuine absence of humpback dolphins.

If you are in one of these countries and have information on a dolphin sighting or stranding, use this map to find the relevant contact details for the person collecting data in your country, or email us at for help connecting to the relevant research and conservation organisations.
