(total): 16 - 19;
soft rays: 6 - 8;
Vertebrae: 34. This species is characterized by the following: small mouth, somewhat ventral on head; fleshy lips, upper lip projecting, maxilla reaching a vertical through posterior nostril; small teeth, mainly tricuspid, a few lanceolate, in 3-4 rows in jaws, with outermost row largest; vomerine teeth in small patch; nostrils 2 pairs, anterior pair with fleshy tentaculate flaps on anteroventral margin and posteroventral margin; opercle with broad flat spine, does not extend to the fleshy margin; scales are small, cycloid, embedded, extending on to cheeks and opercles, and forming a sheath along base of spinous dorsal fin (Ref. 86913).
Inhabits weedy reef slopes (Ref. 9002). Feeds on algae (mainly red, Ref. 86913), and the small invertebrates living amongst it. A poor food fish with its flesh described as coarse with a rank flavor (Ref. 86913).
