Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 4 - 5; Rückenflossenweichstrahlen (insgesamt): 25-26; Afterflossenstacheln 2; Afterflossenweichstrahlen: 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

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
