Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 80-84; Raggi anali molli: 48 - 52; Vertebre: 52 - 53. This species is distinguished from its congeners by having predorsal scales and by the following set of characters: pair of frontal spines above and behind eyes is more or less distinct and a median, sub-dermal, cartilaginous, ethmoidal spine in front of eyes; numerous neuromasts found below translucent head-skin arranged in four distinct clusters; with scales on body; anterior arch with 3 long gill rakers, 3-5 times length of filaments; prolonged pectoral peduncle; palatines with 2- tooth rows; lower angle of preoperculum with an antero-ventrally directed spine; vertebrae, precaudal 12-13, total 52-53; fin rays, D 80-84, A 48-52, pectoral 17-18; otolith length to height, 1.9, otolith length to colliculum length, 2.8-3.1 (Ref. 93007).

This viviparous species occurs on the upper continental slope. Female specimens have extended ovaries and eggs up to 0.5 mm in diameter; no embryos were observed. A 5.0 cm SL male paratype had a ripe testes and well developed intromittent organ (Ref. 93007).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00179 - 0.01169), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±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).
