Etymology: Aluterus: Name from Greek meaning not free or detached, referring to the pelvis that does not form a spiny project (as it does in triggerfish) (R. Chandler, pers. Comm. 10/2014).. More on author: Linnaeus.

Circumtropical. Western Atlantic: Massachusetts, USA to Argentina (Ref. 36453). Eastern Atlantic: west coast of tropical Africa (Ref. 3592).

Max length : 76.2 cm TL オス/雌雄の選別がない; (Ref. 26340); common length : 40.0 cm TL オス/雌雄の選別がない; (Ref. 3467); 最大公表体重: 2.7 kg (Ref. 40637)
背面の脊椎 (合計): 2; 背鰭 (合計): 45-52; 肛門の骨 0; 臀鰭: 47 - 53. Rudimentary pelvic spine disappears in large specimen (Ref. 36453). Snout convex in adults (Ref. 1602). Sandy to grey with small brown spots above; soft dorsal and anal fins pale yellowish to brownish; caudal membrane blackish brown (Ref. 4421).
Occasionally in shallow water by steep drop-offs. Solitary or in pairs, occasionally in groups of five or six, at less than 10 m depth. Juveniles are pelagic, seen under floating objects (Ref. 9318, 48637). Benthopelagic (Ref. 58302). Adults and juveniles are rarely seen near reefs. Juveniles often with large jellies and these may bring them close to reefs and adults may nest on sandflats adjacent to reefs in deep water. At other times, the adults may form large schools under weed-rafts that usually form during the wet season (Ref. 48637). Feed on benthic organisms (Ref. 30573).
