Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 16 - 18; Radios blandos dorsales (total) : 11; Espinas anales: 1; Radios blandos anales: 19 - 20; Vértebra: 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).
Body shape (shape guide): elongated.
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).
