Description

Eleotris daganensis is a sleeper goby (family Eleotridae) of West Africa. The species reaches about 12 cm and has an elongate, dark brown body with a blunt head. It lives in brackish and fresh coastal rivers and the lower reaches of watercourses. As a nocturnal ambush predator it hunts small fishes, crustaceans and insects. The species tolerates varying salinity and is of little commercial value. It is harmless to humans. Little is known in detail about its reproduction, though many sleepers have a planktonic larval stage.
