Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 15 - 17; Raggi dorsali molli (totale) : 10 - 12; Spine anali: 1; Raggi anali molli: 19 - 21; Vertebre: 35 - 36. Dorsal fins III + XII-XIV + 10-12 (usually III + XIII + 10-11); anal fin I, 19-21 (usually 20); pectoral fins usually 15-17 (usually 16: 2, 7, 7). Lateral line continuous, tubed scales 21-27, ending below anterior part of third dorsal fin; total lateral scales 38-40 (37-41, from Clark). Nape, belly, and bases of first dorsal and anal fins scaleless; caudal fin with 1 or 2 rows of scales at base. Pelvic-fin rays bound together by membrane for half the length of shorter ray, longer ray reaches vent. First dorsal fin, triangular, originates over posterior margin of preopercle, in males first spine about as long as longest spine of second dorsal fin, but shorter in females; first two spines close to each other. Mouth large; maxilla reaches vertical through posterior border of pupil; orbital cirrus very small; dentary pores 3 + 1 + 3; head length 3.0-3.5 in SL (Ref. 88983).
Found usually solitary on corals and rocks in lagoons and bays from 0.5-12 m or deeper (Ref. 88983).
