簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 16 - 18; 背的軟條 (總數) : 11; 臀棘: 1; 臀鰭軟條: 19 - 20; 脊椎骨: 37. Distinguished by the following characters: 5-8 symphyseal mandibular sensory pores; second dorsal fin spines XIII-XIV; last pleural ribs on vertebral centrum 11, vertebrae 11+ 26 = 37; nape naked (Ref. 9849); black lower half of head; bright blue stripe extending from anterior part of upper lip to preopercular margin through ventral margin of orbit; dorsal fins black distally; central part of pectoral fin base black; entire caudal fin black (Ref. 95023).
Adults are found among rocky boulders and in surge channels to a depth of about 6 m (Ref. 9849). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
發現於岩石的大圓石中了與在洶湧的峽道到深度大約 6 公尺中。

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
