Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 13 - 14; членистые (мягкие) лучи спинного плавника (общее число) : 11 - 12; колючие лучи анального плавника: 2; членистые (мягкие) лучи анального плавника: 9 - 10. This species is distinguished by the following set of characters: D XIII-XIV,11-12 (usually 12); A II,9-10 (usually 10); pectoral-fin rays 18-20 (usually 19); pelvic-fin rays I,5; caudal-fin rays principal 15, branched 13; procurrent spiniform caudal-fin rays 2; tubed lateral-line scales 16-19 (usually 18-19); gill rakers 7-11 + 18-23, total rakers 26-33 (usually 26-29) (Ref. 125611).
Adults inhabit lagoon and seaward coral and rocky reefs (Ref. 9710). Prefer habitat consisting of boulder substrates or mixed rock, rubble, and sand, at depths between about 3 and 30 m (Ref. 125611). Oviparous, distinct pairing during breeding; eggs demersal and adhere to the substrate, and males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699).
