Etymology: Trachinotus: Greek, trachys, -eia, -ys = rough + Greek,noton = back (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; depth range 1 - 7 m (Ref. 5439). Tropical; 31°N - 35°S, 30°E - 157°W
Indo-Pacific: Red Sea and East Africa (Ref. 3287) to the Marshall Islands and Samoa, north to southern Japan, south to Australia.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 58 - ? cm
Max length : 110 cm FL male/unsexed; (Ref. 1602); common length : 40.0 cm TL male/unsexed; (Ref. 3280); max. published weight: 3.4 kg (Ref. 40637)
Juveniles inhabit sandy shorelines and shallow sandy or muddy bays near river mouths while adults move out in schools to clear seaward coral and rock reefs (Ref. 5213). Juveniles are in small schools, while adults are usually solitary (Ref. 48635). Adults feed primarily on sand mollusks and other hard-shelled invertebrates (Ref. 9710).
