Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 9; Mjukstrålar i ryggfenan (totalt): 18-21; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 15 - 17; Ryggkotor: 24. This species is distinguished by the following characters: gill rakers (including rudiments) 5-7 + 15-17 = 20-24; breast naked ventrally, typically with a small to large patch of prepelvic scales; colour in life of adults, head and body silvery grey to black above, usually paler below; fins usually uniformly grey to black, fish from turbid coastal waters often with yellow fins, the anal fin usually brightest (Ref. 9894).

Biologi     Ordlista (t.ex. epibenthic)

Adults are pelagic over sand and rock (Ref. 58302). They 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). Juveniles are found in estuaries. Large individuals may be ciguatoxic. The largest trevally reaches 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). Sold mostly fresh and dried salted.
