Short description Chiavi di identificazione | Morfologia | Morfometria

Raggi dorsali molli (totale) : 69 - 78; Raggi anali molli: 60 - 67; Vertebre: 74 - 81. This species is distinguished by the following characters: body long, robust and slightly compressed; D 69-78, A 60-67, caudal-fin rays 8-10 and pectoral-fin rays 21-25; vertebrae precaudal 34-37, total 74-81; origin of dorsal fin above vertebra 27-30, anterior gill arch with 27-32 long rakers; fangs on vomer 3-5 and on each dentary 3-5; predorsal length 47.0-52 % SL; otolith small (3 mm long in 20.0 cm SL holotype). Colouration: pigment laterally on body absent, dark blue peritoneum and newly caught specimen reddish all over (Ref. 128809).

Maximum length of ripe female 20.0 cm SL caught by demersal trawl and unripe male, 8.5 cm SL collected at 1191-1262 m by an otter trawl (Ref. 128809).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00172 - 0.01163), 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): 3.5 ±0.5 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 (14 of 100).
