Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino associati a barriera corallina; distribuzione batimetrica 1 - 90 m (Ref. 37816), usually 15 - 30 m (Ref. 9680). Tropical; 30°N - 30°S
Indo-Pacific: East Africa to the Society Islands, north to southern Japan, south to New South Wales. Not present in Hawaii (Ref. 9680). Southeast Atlantic: southeast coast of South Africa (Ref. 4423).
Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 65.0 cm TL maschio/sesso non determinato; (Ref. 9710)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 14 - 16; Spine anali: 0; Raggi anali molli: 14 - 16. Spines short (Ref. 1602). Several yellow-edged dark blotches on body (Ref. 559). D. liturosus differs from D. hystrix by its shorter spines and color (Ref. 37816).
Inhabits reef edges and slopes (Ref. 6113, 48637). Hides in caves and ledges during the day and forages at night (Ref. 9680). Also found below plate-corals during the day and often deep, ranging to at least 40 meters depth. Juveniles occur in lagoons and estuaries (Ref. 48637). Solitary. Feeds on crustaceans and mollusks. Not usually marketed (Ref. 9680).
