Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm TL male/unsexed; (Ref. 2334)
(total): 11 - 12;
soft rays: 16 - 18. Dorsal fin XI-XII (typically XII), 14-16 (typically 15). Anal fin II,16-18 (typically 17). Pectoral fin 12 or 13 (rarely 12). Segmented caudal-fin rays 13. Vertebrae 10 or 11 (rarely 11) + 21-24 (rarely 21, usually 23) = 31-34. Dentary incisor teeth which includes anterior canine teeth very similar in appearance from incisors, 45-53; posterior dentary canines (specimens at least 25 mm SL) 3-8 on each side (rarely 3). Lateral line lacking pairs of pores, terminating posteriorly at point between verticals from dorsal-fin spines 9 and 11 (rarely surpassing vertical from 9). With cirrus on posterior rim of anterior nostril; absent on anterior rim.
Adults are found on coastal reefs (Ref. 2334). 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).
