Greasy grouper (Epinephelus tauvina), Red Sea, Egypt. The species inhabits clear-water areas on coral reefs (at depths to 50 metres (160 ft)), although juveniles may venture into reef flats, tidepools, and mangrove estuaries. The greasy grouper occurs in the Red Sea and along the East African coast, east to the Pitcairn group, north to Japan, and south to Lord Howe Island. Epinephelus tauvina grows up to 75 cm (30 inches) in length and is a protogynous hermaphrodite. Greasy groupers are top predators on the reef; they mainly feed on small fish and sometimes crustaceans. The greasy grouper is caught in recreational fisheries (including spearfishing and hook-and-line fishing) and plays a major role in commercial fisheries. It is also found in the aquarium trade.
