Description synthétique Morphologie | Morphométrie

Rayons mous dorsaux (Total): 15-16; Rayons mous anaux: 13 - 14; Vertèbres: 46 - 48. In fish measuring 6 cm SL or more, aggregation of luminous tissue on head appear as a band across gill cover; one or several luminous patches on flanks, close to the medial line of body in advance of pelvic fin insertion. Chin barbel shorter than head, its swollen tip forming wide flattened lobe with oblique ribs and with small medial notch. It differs from other species of the group in having more vertebrae (Ref. 27676).

Estimates based on models

Preferred temperature (Ref. 123201): 20.9 - 28.6, mean 26.5 °C (based on 73 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).

Niveau trophique (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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