About the East Coast Fish-Watch Project
The fish fauna of the east coast of South Africa is a mixture of tropical Indo-West Pacific (mainly coral-reef species) and many endemic warm-temperate species. This fauna is not well known, and in the past 20 years our fish survey work has produced numerous range extensions, many new records and several new species. In addition to our own collecting efforts and those of fisheries biologists on South African research vessels, observers on fishing vessels, and fishing companies, our knowledge of the South African fish diversity is significantly enhanced by the specimens and photographs provided by various amateur ichthyologists (divers, anglers, aquarists and underwater photographers).
The endemic ornate sleeper ray, Electrolux addisoni. Photograph by Peter Chrystal taken at Aliwal Shoal.
A new sleeper ray (Family Narkidae) was first made known to scientists by diver-photographer Peter Chrystal (through Rudy van der Elst), who photographed this spectacular ray on a patch of sand on Aliwal Shoal in 1984. The ray was subsequently rediscovered on Protea Banks off Shelly Beach, KZN in 1997 by underwater photographers Stephania and Peter Lamberti who sent us a video-clip of the ray. It has also been photographed underwater at the T-Barge north of Durban by Dennis King and at Aliwal Shoal by Len and Avril Fish, and Allen Walker. A live specimen of the ornate sleeper ray was seen underwater by Phil and Elaine Heemstra at Coffee Bay, Eastern Cape, but it fled before Phil could net it.
