Description

The blacktip grouper is a common reef grouper of the family Serranidae reaching about 52 cm. The reddish-brown body bears several dark cross-bands and has characteristic black tips on the dorsal-fin spines; the colour can quickly pale or intensify. Like many groupers it is a protogynous hermaphrodite: individuals begin as females and later become males. The species is widespread in the Indo-Pacific and lives near rocky bottoms and coral reefs of coastal water. As an ambush predator it darts from cover at crustaceans and small fish and sucks them in with a wide-gaping mouth. With its tasty flesh it is a valued commercial and sport fish.
