Etymology: Heteropriacanthus: Greek, heteros = other + Greek, prion = saw + greek, akantha = thorn (Ref. 45335).
More on author: Lacepède.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 300 m (Ref. 27000), usually 3 - 35 m (Ref. 40849). Subtropical; 33°N - 32°S, 180°W - 180°E
Atlantic and SW Indian Ocean: restricted. Former circumglobal distribution now accounted to former synonyms H. carolinus (widespread in the Indo-Pacific region) and H. fulgens (northeastern Atlantic Ocean).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.7 cm TL male/unsexed; (Ref. 9990); common length : 20.0 cm SL male/unsexed; (Ref. 55763); max. published weight: 2.7 kg (Ref. 9990)
soft rays: 13 - 14. Silvery pink, mottled red or solid red in color; median fins with faint dark dots. Pelvic fins dusky or pale and without distinct spots (Ref. 4328). Section of preopercle behind canal striated and without scales (Ref. 26938).
Common in lagoon and seaward reefs, primarily around islands. Under or near ledges by day (Ref. 9710). Benthopelagic (Ref. 58302). Juvenile pelagic (Ref. 9335). Nocturnal (Ref. 5213), feeding mainly on octopi, pelagic shrimp, stomatopods, crabs, small fish, and polychaetes. Solitary (Ref. 5213). During the day usually occurs singly or in small groups but at dusk it may gather in large numbers (Ref. 37816). Known to produce sound. Marketed fresh (Ref. 3800). Minimum depth reported taken from Ref. 30874.
