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.
Click on the outlines of the highlighted countries in the interactive map to reveal the country name and to access country-specific information on: the current distribution and conservation status of Atlantic humpback dolphins, a list of peer-reviewed articles and reports, and information about local researchers and conservation organisations.
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 info@sousateuszii.org for help connecting to the relevant research and conservation organisations.
