Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 10 - 11; Rayons mous anaux: 7. Can be diagnosed by the following characters: smooth and scalesless body; tapering and relatively narrow head, head width 47.6-54.0% HL; eye diameter 12.1-17.6% HL; thin and smooth lips; slender and laterally compressed trunk; caudal-peduncle length 20.0-23.8% SL; slender, laterally compressed (cross-section of caudal peduncle elliptic) and tapering caudal peduncle , with trunk towards the base of caudal fin; pelvic fin insertion anterior to dorsal-fin origin; dorsal-fin origin closer to caudal-fin base than to snout tip; caudal fin deeply concave; lateral line complete; posterior chamber of gas bladder reduced or absent; intestine short, in zigzag pattern posterior to bottom of ‘U’-shaped stomach (Ref. 92369).

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=0.00776 (0.00448 - 0.01346), b=2.94 (2.79 - 3.09), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).

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