Description
Dorsal spines (total): 9; Dorsal soft rays (total): 11; Anal spines: 3; Anal soft rays: 10; Pectoral fin rays: 14-15 (usually: 14) Lateral line scales: 46-49 (+2 past hypural). Postorbital head and posterior suborbital with small scales (none extending anterior to centre of eye); Lips thick and fleshy, forming a tube when mouth closed; Front upper jaw with two pairs of large recurved canine teeth, the second pair about half as long as first, and a large canine posteriorly, with no teeth between; Front lower jaw with a pair of large recurved canines, followed by 2-3 lesser canines. No free lower preopercular margin; Body depth: 3.4-3.8 in SL; Caudal fin of juveniles rounded, of females truncate with rounded corners, of males emarginate; Pelvic fins short, not reaching anus.
