Description

The highfin grouper is a grouper from the Pacific, from the Cocos-Keeling Islands to Samoa, north to Japan and south to southeastern Australia. The species grows to about 60 cm and has a pale brown body with numerous small dark and light spots. As a bottom-dweller it lives on coral and rocky reefs to about 100 metres and hunts sand-dwelling fish, crustaceans and sometimes octopus. Like other groupers it is a protogynous hermaphrodite. Large specimens can cause ciguatera poisoning in some areas. The IUCN assesses the species as Least Concern (LC).
