背棘 (总数): 12 - 13; 臀棘 2; 臀鳍软条: 15 - 17; 脊椎骨: 31 - 33. Dorsal fin XII or XIII (rarely XIII), 13-15, deeply incised between spinous and segmented-ray areas. Anal fin II,15-17. Pectoral fin 12-14 (rarely 12 or 14). Segmented caudal-fin rays 13. Vertebrae 10 + 21-23. Dentary incisor teeth which includes anterior canines very similar in appearance from incisors, 46-54 in males and 48 to 56 in females, averaging more in females than males; posterior canines 0 or 1 (usually 1). Lateral line without vertical pairs of pores, extending posteriorly to point between vertical from interspace between 9th and 10th spines and vertical from base of 11th dorsal-fin spine (rarely anterior to base of 10th spine). With cirrus on posterior rim of anterior nostril; absent on anterior rim. Posterior portion of body with sparse peppering of fine, dark spots (Ref. 5296).
Adults feed mainly on a diet of coral polyps and mucous (Ref. 94105). 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).
