Short description Morfologia | Morfometria

Spine dorsali (totale): 3; Raggi dorsali molli (totale): 14-16; Spine anali 1; Raggi anali molli: 8 - 9; Vertebre: 26 - 27. This species is distinguished by the following characters: gill rakers on first gill arch 15-18; width of suborbital bone is substantially larger than eye diameter; vertebrae 26-27, including 11 (rarely 12) abdominal vertebrae; spurs on haemal arch of first caudal vertebra; D III,14-16; A I,8-9, soft rays in pelvic fin 7; pelvic fin origin under vertical (or behind of the vertical) through posterior edge of pectoral fin base; anal fin origin under second to fifth rays of dorsal fin (from end of fin); no black dotted pigmented spots on head, body, and fins (Ref. 117122).

Trawled at depths greater than 125 meters (Ref. 4241).

Estimates based on models

Preferred temperature (Ref. 123201): 15.2 - 23.7, mean 20.9 °C (based on 46 cells).

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

Bayesian length-weight: a=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.38 se; based on food items.

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).
