Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 16 - 18; Raios dorsais moles (total) : 11; Espinhos anais: 1; Raios anais moles: 19 - 20; Vértebras: 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).

Nível Trófico (Ref.
69278): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
