Short description

Dorsal spines (total): 11; Dorsal soft rays (total): 16-17; Anal spines: 3; Anal soft rays: 8. Juveniles are mostly yellow becoming gray with dark spots anteriorly. The gray area increases with increasing size until only the fins remain yellow on individuals of 15 to 20 cm (Ref. 37816).

Biology     Glossary (e.g. epibenthic)

Usually found around isolated coral heads in lagoons or bays, but also caught on outer reef area. According to Myers (1989, Ref. 4538) it usually swims out in the open, several meters above the bottom. It is readily caught by anglers at night. Feeds mainly on sand-dwelling fishes and crustaceans such as snake eels and box crabs. In Hong Kong live fish markets (Ref. 27253).

IUCN Red List Status (Ref. 90363)

Threat to humans

  Reports of ciguatera poisoning (Ref. 1602)
