Γεννητική Ωρίμανση: Lm ? range ? - ? cm
Max length : 60.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 55); common length : 50.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 55)
Ραχιαίες άκανθες (συνολικά) : 10; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 14; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 8 - 9. This species is distinguished by the following characters: body moderately deep to somewhat slender; greatest depth 2.6-3.0 in SL; preopercular notch and knob poorly developed; vomerine tooth patch crescentic, without a medial posterior extension; tongue smooth, no teeth; gill rakers of first gill arch 7 + 11-12 = 18-19 (including rudiments); caudal fin truncate to slightly emarginate; scale rows on back rising obliquely above lateral line. Colour generally whitish to pinkish with dusky scale margins; grey or brown on upper back and dorsal portion of head, a black spot, sometimes faint or absent, on back below anterior soft dorsal-fin rays (in juveniles, the spot is round and gradually shrinking and becoming horizontally elongate with increased growth); fins yellowish (Ref. 9821, 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Adults inhabit coral reef areas, usually close to shelter in the form of caves, large coral formations and wreckage. Usually solitary; occasionally occurring in small groups. They feed mainly on fishes and benthic crustaceans, primarily crabs (Ref. 37816) at night. Flesh is sometimes ciguatoxic, and commonly so in Tuvalu (Ref. 9513).
