Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 37; Raggi anali molli: 30; Vertebre: 41. This species is distinguished by the following set of characters: projecting lower jaw anterior to upper jaw; distinct flaps and folds of skin on snout, upper jaw, and ventral portion of mandible; large pelvic disc 37.4% HL; slender body; depth at pectoral fin base 20.5% SL, at anal-fin origin 19.0% SL; 2-6-8-1 pattern of cephalic lateralis pores, no coronal and post coronal pores; 2 epurals that are fused at the base; autogenous hypural plates; with pleural ribs; no pseudobranchiae; no subcutaneous layer; no pyloric caeca (Ref. 57784).

Species typical of moderately deep waters. Holotype had ostracods and rocks found in its stomach (Ref. 57784). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 3.7 - 4.1, mean 3.8 °C (based on 5 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00237 - 0.01161), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

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