Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 1; Raggi dorsali molli (totale) : 9 - 11. Body light grey in color; head silvery blue on top and sides, darker below and on gill covers (Ref. 3974). Lack of scales on the dorsal surface of the head and short maxillary spine (Ref. 37108).

Found between 530-2321 m, associated with islands and continental slopes (Ref. 58302). Found at bathyal to abyssal depths. Feeds on amphipods, mysids, copepods and polychaetes. Sexually dimorphic, maturing males have enlarged nostrils, anterior nostrils are black and tubular. Females outnumber males 4:1 in western North Atlantic.

Estimates based on models

Preferred temperature (Ref. 115969): 2.5 - 8.8, mean 5.3 (based on 1006 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00087 (0.00033 - 0.00229), b=3.07 (2.84 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.34 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming tmax>10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
