Taggstrålar i ryggfenan (totalt) : 11 - 13; Mjukstrålar i ryggfenan (totalt) : 13 - 15; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 15 - 17; Ryggkotor: 31 - 33. Dorsal fin XI-XIII.13-15 (rarely XI, XIII, or 15); incised between spinous and segmented-ray portions. Anal fin 11,15-17 (rarely 17). Pectoral fin 12-14 (usually 13). Segmented caudal-fin rays 13. Vertebrae 10 + 21-23. Dentary incisor teeth which includes anterior canines very similar in appearance with incisors, 49-59 in males and 53 to 63 in females, averaging more in females than males; posterior canines 0 or 1 (typically 1). Lateral line lacking vertical pairs of pores, extending posteriorly to point between verticals from 9th and 11th dorsal-fin spines, typically extending to or beyond 10th spine. With cirrus on posterior rim of anterior nostril; absent on anterior rim.
Body shape (shape guide): elongated; Cross section: oval.
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).
