Description

The longfin grouper is a grouper of the family Serranidae from the western Pacific. The species grows to about 40 cm and has a pale body densely covered with brown, honeycomb-like spots, with a dark blotch at the pectoral-fin base. It inhabits inshore, silty reefs and is not found deeper than about 50 metres. As an ambush predator it feeds on shrimps, small fishes and other crustaceans. Groupers are often protogynous hermaphrodites, starting as females and later able to become males. The longfin grouper is a valued food fish and harmless to humans.
