Description

The Pacific mutton hamlet is a small grouper of the family Serranidae from the eastern Pacific. The species grows to about 30 cm and has a stocky, mottled brown-red body with fine speckling, camouflaging it well. It is a shy, retiring species of shallow waters that hides among rocks, coral and vegetation by day. As a nocturnal ambush predator it feeds on small crustaceans and small fishes. Like many groupers it is probably a protogynous hermaphrodite. The species is a local food fish and is harmless to humans.
