Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm TL male/unsexed; (Ref. 2272)
(total): 12 - 14;
soft rays: 18 - 21;
Vertebrae: 35 - 37. Dorsal fin typically XIII, 16-19 (rarely 16 or 19), spinous and segmented-ray portions with moderate notch in-between. Anal fin II,18-21 (rarely 18 or 21). Pectoral fin 13-15 (rarely 13, typically 14). Segmented caudal-fin rays 13. Vertebrae 10 or 11 (rarely 10) + 24-26 (rarely
24) = 35-37 (rarely 35). Dentary incisor teeth which includes anterior canine teeth very similar in appearance with incisors, 44-54; posterior dentary canines 0 or 1 (typically 1) on each side. Lateral line lacking pairs of pores, terminating posteriorly at a point between verticals from dorsal-fin spines 8 and 11 (rarely as far anteriorly as 8). With cirrus on posterior rim of anterior nostril; absent on anterior rim. Two color patterns: pale (northern) and dark (southern).
Mimics Meiacanthus nigrolineatus (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).
