Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 3 - 250 m (Ref. 30573), usually 15 - ? m (Ref. 5222). Tropical; 30°N - 37°S, 30°E - 23°W (Ref. 5222)
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 41 - ? cm
Max length : 83.0 cm TL male/unsexed; (Ref. 40637); common length : 75.0 cm TL male/unsexed; (Ref. 5450); max. published weight: 12.0 kg (Ref. 5222)
Indo-Pacific: Red Sea to South Africa and the Pitcairn Islands, north to southern Japan, south to New South Wales, Australia. Not found in the Persian Gulf nor in Hawaii.
Usually seen in clear-water areas at depths below 15 m, and prefers islands and offshore reefs rather than continental shores. Feeds mainly on fishes, and on crabs, shrimps and stomatopods. It is highly appreciated for the quality of its flesh. It may not be sold in Mauritius because of cases of ciguatera poisoning (Ref. 11888). In the Hong Kong live fish markets (Ref. 27253).
