Description

The bigeye grunt is a silvery fish of the family Haemulidae (grunts) reaching about 30 cm. The laterally compressed body stands out for large eyes and a yellowish tinge; like other grunts it can make a grunting sound with its throat teeth and swim bladder. The species forms enormous schools over sand and mud bottoms of the continental shelf along the West African coast. In the water above the bottom it feeds on zooplankton, small crustaceans, worms and small fish. Through its great numbers the bigeye grunt is one of the most important commercial fish of the West African coastal fishery and a main prey for larger predators.
