Distribution

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. It is not common in Fiji, Tonga, or French Polynesia. Records from the South China Sea, Taiwan, Australia, and various islands off North America exist.

Habitat

The species inhabits clear-water areas on coral reefs (at depths to 50 m), although juveniles may venture into reef flats, tidepools, and mangrove estuaries.

Description

Epinephelus tauvina grows up to 75 cm (30 inches) in length. These fish have a wide, upward-facing mouth with rather thick lips. Their heads and bodies are pale greenish grey or brown with round spots, varying from orange-red to dark brown.

A group of black spots may be visible on the body at the base of the rear of the dorsal fin. Five vertical darker shaded bars may also be present on their bodies.

It is similar to E. corallicola and E. howlandi, which, however, have shorter bodies and spots less closely spaced.

Due to confusion about identifying species, much of the earlier (particularly before 1984) literature referring to E. tauvina may actually refer to other species of grouper, including Epinephelus coioides, Epinephelus malabaricus and Epinephelus lanceolatus.

Biology The greasy grouper is a long-lived fish with a very slow growth rate. It is a protogynous hermaphrodite. Greasy groupers are top predators on the reef; they mainly feed on small fish and sometimes crustaceans.
