Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 4 - 5; Raios dorsais (total) : 25 - 26; Espinhos anais: 2; Raios anais : 15 - 16. Lunate caudal fin with elongated lobes in both sexes; upper half of body bluish black and lower half abruptly bluish white, posteriorly with few small black spots; dorsal fin basal half black with pale blue stripe composed of 1 spot per membrane broadly joined to the next ; outer half of fin bluish gray with pale thin blue margin and black submarginal line; caudal fin base and lobes black with pale blue upper and lower margins, centroposterior part of fin transparent with dusky rays; pectoral-fin axil without dark spot. Dorsal rays IV-V (rarely IV), 25-26; pectoral soft rays rarely 13; segmented caudal rays 11-12 (typically 11); lateral line present (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).

Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.4 ±0.4 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.
