Biology     Glossary (e.g. epibenthic)

Pelagic over sand and rock (Ref. 58302). Adults occur singly and inhabit clear lagoon and seaward reefs (Ref. 9710). They feed on crustaceans (like crabs and spiny lobsters) and fishes at night (Ref. 4887). Large individuals may be ciguatoxic. The largest trevally, reaching 1.7 m in length and a weight of over 60 kg (Ref. 48635). Spawning occurs on shallow seaward reefs and offshore banks (Ref. 37816). Juveniles are found in estuaries. Sold mostly fresh and dried salted.
