Reef-building corals (Cnidaria: Scleractinia) from the Watamu Marine National Reserve, Kenya; an annotated species list

The scleractinian fauna of the Watamu Marine National Reserve, Kenya, was surveyed between November 1982 and April 1983. The survey yielded 276 specimens representing 113 species in 45 genera, which are presented in an annotated checklist. Four genera and 43 species are added to the the list of previously known Scleractinia for East-Africa, bringing the number of species recorded for this region to 169. This substantial increase, as well as the high coral diversity of nearby communities, suggests that further additions can be expected.
