Etymology: Priacanthus: Greek, prion = saw + Greek, akantha = thorn (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 15 - 30 m (Ref. 9710), usually 25 - m (Ref. 30573). Tropical; 0°C -
Indo-Pacific: Gulf of Aden to Samoa, north to the Philippines and south to the Great Barrier Reef. Often confused with the wide-ranging Priacanthus hamrur. Reports from Taiwan are misidentifications of Priacanthus sagittarius (in Lee, 1980) and Heteropriacanthus cruentatus (in Shen, 1984).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 30573)
Occurs in lagoon and seaward reefs, under ledges or in caves by day (Ref. 9710); often silty habitat (Ref. 48635). Solitary or in small groups (Ref 90102). Rarely trawled (Ref. 30573).
