The Longfin grouper (Epinephelus quoyanus) is a marine fish of the family Serranidae.

Biology

Inhabits inshore silty reefs; there are no records from depths greater than 50 m. Feeds on crustaceans, fishes, and worms. The enlarged fleshy pectoral fins appear to have resulted from its habit of sitting on the substrate.
