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; 0°C - ; 33°N - 32°S, 180°W - 180°E
Circumglobal in tropical and tropically influenced seas. Western Atlantic: continental waters from off Florida to Flower Garden Reef off Texas in the Gulf of Mexico; Caribbean islands and along the coast of South America to Argentina. Eastern Atlantic: eastern and mid Atlantic islands from Madeira to St. Helena; not recorded from African continental waters. Indo-Pacific: South and eastern Africa (excluding the Red Sea) eastward in island habitats through the central Pacific. Eastern Pacific: island habitats from off Baja California to the Galapagos; probably uncommon along coast of Mexico, Central and South America, questionably to Chile.
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.
