Descrição breve Chaves de identificação | Morfologia | Morfometria

Raios dorsais moles (total) : 17 - 20; Raios anais moles: 13 - 15; Vértebras: 46 - 48. This species is characterized by having the IP photophores curved rather than linear; presence of a luminous tissue prominent on gill cover between preopercle and opercle in larger specimens (SL > 50 mm), lower part more prominent than upper; posterior part of lower jaw with a pair of prominent irregular luminous tissues; moor luminous head, jaws, dorsum, and body; chin barbel long, about 0.2-0.8 times head length, increasing with fish size; terminal end of barbel slightly swollen, apical tip rounded (Ref. 75891).

Estimates based on models

Preferred temperature (Ref. 123201): 6.5 - 11.6, mean 8.3 °C (based on 47 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00417 (0.00171 - 0.01014), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.7 ±0.6 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. 59153): Low vulnerability (10 of 100).
