Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 5 - 7; Raggi dorsali molli (totale) : 12 - 15; Spine anali: 4; Raggi anali molli: 15 - 17. First infraorbital without spine on anterior end. Lateral line ends in caudal fin base. No fleshy disk on inner face of exposed area of scale. Anterior and posterior nostrils close together, their distance apart shorter than diameter of anterior nostril. Specimens from the Indian Ocean have more gill rakers than specimens from Japan.

A benthic or benthopelagic species trawled in 128-200 m depth.

Estimates based on models

Preferred temperature (Ref. 123201): 14.7 - 22, mean 19.2 °C (based on 40 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5088 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01288 (0.00587 - 0.02825), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
