Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 13; Raios dorsais moles (total) : 17 - 20; Espinhos anais: 2; Raios anais moles: 19 - 22. Lip margins smooth; females dorsally whitish to light gray and ventrally white with a series of 6 paired black spots (anterior 2 pairs irregular with a row of spots above) on upper side of body, and 1 spot on caudal peduncle, each connected by a gray bar to a lower series; a black line on back at spinous portion of dorsal fin, and 4 pairs of small black spots along base of soft portion; small bluish white spots on posterior half of body, mostly on upper half; narrow black bars ventrally on head angling on to throat; a white line at posterior edge of eye continuing below to upper lip; median fins with blackish margins; posterior part of crest with a narrow pink margin and a broad, submarginal black band; dorsal-fin base with alternating black and whitish blotches; a black spot at midbase of caudal fin; males similar except with darker body; bluish white spots on body generally elliptical; faint oblique black bands on throat; oblique white lines in soft portion of dorsal fin. Last spine of dorsal fin very small; dorsal soft rays usually 19; anal soft ray rarely 19 or 22; middle 6-9 of 14 segmented caudal rays branched; lateral-line pores 5-9 (Ref. 54980).

Biologia     Glossário (ex. epibenthic)

Facultative air-breathing (Ref. 126274); Adults are found in tidepools (Ref. 54980). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Bayesian length-weight: a=0.00741 (0.00335 - 0.01640), b=3.02 (2.83 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  2.0   ±0.00 se; based on food items.
Resiliência (Ref. 120179):  Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
