Description

The mutton hamlet is a sea bass (Serranidae) from the western Atlantic and the Caribbean. The species has a stocky, red-brown mottled body that camouflages it among vegetation. It is a solitary inhabitant of seagrass beds and rocky coastal waters. By day it is little active and hides in crevices or among seaweed; at night it hunts as an ambush predator for crustaceans and small fishes. The species is harmless to humans.
