Description

The mottled grouper is a robust grouper of the family Serranidae reaching about 1.4 metres. The stout, red-brown body is mottled with pale spots; juveniles have conspicuous pale longitudinal stripes on the head. The species lives over rocks, reefs and caves of the Mediterranean and the eastern Atlantic. As a territorial ambush hunter it seizes fish, squid and crustaceans. Like many groupers it is a protogynous hermaphrodite: it starts as a female and later becomes male. It grows slowly and matures late, which makes it sensitive to fishing; it is therefore assessed as Near Threatened (NT). The mottled grouper is a valued sport and food fish.
