(Puffers and filefishes) > Monacanthidae
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)..
Environment: milieu / climate zone / depth range / distribution range
marino associati a barriera corallina; distribuzione batimetrica 3 - 120 m (Ref. 36484), usually 3 - 20 m (Ref. 40849). Subtropical; 46°N - 30°S, 180°W - 180°E
Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 110 cm TL maschio/sesso non determinato; (Ref. 9710); common length : 55.0 cm TL maschio/sesso non determinato; (Ref. 5450); peso massimo pubblicato: 2.5 kg (Ref. 26340)
Spine dorsali (totale): 2; Raggi dorsali molli (totale): 43-50; Spine anali 0; Raggi anali molli: 46 - 52. Snout concave (Ref. 1602); olive brown to grey in color, juveniles may be yellowish brown with dark spots (Ref. 4421). Elongate, strongly compressed filefish; tan with blue lines and spots. Caudal fin rounded (Ref. 26938) and long (Ref. 13442). Gill opening oblique, pelvic terminus rudimentary or absent; body and head with scattered small black spots (Ref. 13442).
Inhabit lagoon and seaward reefs (Ref. 9710). Occasionally are seen under floating objects (Ref. 1602). Juveniles may travel with weed rafts in open ocean for a long time and reaching a large size. Adults are usually seen along deep coastal slopes or outer reef drop-offs in about 20 meters depth (Ref. 48637). Benthopelagic (Ref. 58302). Feed on algae, seagrass, hydrozoans, gorgonians, colonial anemones, and tunicates. Caught at the surface using a hand net (Ref. 26165).
