Government of South Africa

South Africa has an extensive coastline in the southern section of Agulhas and Somali Current Large Marine Ecosystem (ASCLME) region, with the coastal provinces of KwaZulu Natal (KZN), Eastern Cape and Western Cape forming the seaboard. The southeast coastline is remarkably linear, with a narrow continental shelf descending to an abyss (deeper than 4,500 m) in the southern Transkei Basin.
