Atlantic humpback dolphins

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 Angola in the south and Dakhla Bay, south of Morocco in the north. 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.
