Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 2272)
(total): 10 - 13;
soft rays: 17 - 22;
Vertebrae: 34 - 37. Dorsal fin X-XIII (typically XII), 18-21 (rarely 21), spinous and segmented-ray portions continuous. Anal fin II,17-22 (typically 19-21). Pectoral fin 14-16 (typically 15). Segmented caudal-fin rays 13 or 14 (rarely 14). Vertebrae 10 or 11 (rarely 10) + 23-26 (rarely 23) = 34 to 37 (rarely 34). Dentary incisor teeth which includes anterior canines very similar in appearance with incisors, 40-53 (rarely < 44); posterior canines 0 or 1(usually 1) on each side. Lateral line lacking vertical pairs of pores, extending posteriorly to point between verticals from 8th and 12th from anterior most dorsal-fin spine (usually past vertical from 8th). With cirrus on posterior rim of anterior nostril; absent on anterior rim. Body coloration of 3 basic color patterns: uniformly brown, dark-brown or black but pigmentless posterior of dark caudal fin base, or generally brownish with darker stripe along dorsal area.
Adults are found among corals (Ref. 9710). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
