Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 14; Espinas anales: 0; Radios blandos anales: 11 - 12. This species is distinguished by the following characters: anal fn is entirely behind the dorsal fin; multiserial teeth on premaxillary, maxillary, and dentary; predorsal scale rows > 70; longitudinal scale rows > 110; dorsal to lateral line scale row > 15; anal to lateral line scale rows > 17; branchiostegal rays 7; dorsal-fn rays < 15; precaudal vertebrae < 30; epurals 2; the lengths of head, snout, upper and lower jaws, orbit diameter, dorsal and anal fn bases are relatively short against standard length (Ref. 123515).

Estimates based on models

Phylogenetic diversity index (Referencia 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00163 - 0.00737), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Referencia 69278):  3.7   ±0.6 se; based on size and trophs of closest relatives
Resiliencia (Referencia 120179):  Muy bajo, población duplicada en un tiempo mínimo superior a 14 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (89 of 100). 🛈
