Description

The rock hind is a grouper of the family Serranidae from the Atlantic. The species grows to about 65 cm and has a pale body densely covered with red-brown spots, with a few dark saddle blotches on the back. It inhabits rocky reefs and is usually solitary and shy; juveniles are often seen in tide pools. As an ambush predator it feeds mainly on crabs and other crustaceans, and on fishes. The rock hind is a valued sport and food fish. Large specimens from tropical areas can contain ciguatera, so do not eat those.
