Short description Claves de identificación | Morfología | Morfometría

Radios blandos dorsales (total) : 75 - 81; Radios blandos anales: 53 - 56; Vértebra: 68 - 71. This species is distinguished from is congeners by the following characters: first gill arch with 3-4 developed gill rakers; D 75-81; precaudal vertebrae 31-32; anal fin origin below vertebrae 32-36. Colouration: black pigmentation laterally in the roof of the mouth, very distinct from the outside as a black area half the head length between the eye and the upper jaw (Ref. 105129).
Cross section: compressed.

All four male specimens with developed reproductive organ indicating internal fertilization, and a tentatively referred specimen is a female with distended, 15 mm long ovaries containing large eggs (0.7 mm) (Ref. 105129).

Phylogenetic diversity index (Referencia 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00172 - 0.01163), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Referencia 69278):  3.4   ±0.5 se; based on size and trophs of closest relatives
Resiliencia (Referencia 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
