Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 2; Spine anali: 0. Head broad, rather soft; snout broad, rounded, with a large blunt tubercular scute at its tip; chin with small barbel. Scales relatively adherent; spinules dense on body scales, long, thin and recurved, narrowly lanceolate, with longitudinal anterior concavity. Pyloric caeca 29 to 31, long and slender. Color medium brown to grayish; orbits, oral and branchial cavities, and fins blackish to brownish gray.

Biologia     Glossario (es. epibenthic)

Benthopelagic to bathypelagic in about 400 and 1200 m depth. Minimum depth from Ref. 1371. Form large schools at 600 to 900 m depth (Ref. 9988). Feed on a variety of fish and invertebrates, but primarily on pelagic crustaceans such as shrimps, amphipods and cumaceans; cephalopods and lantern fishes constitute a lesser portion of the diet. Batch spawner (Ref. 51846). This species is currently facing overexploitation in the North Atlantic. Utilized frozen and for fishmeal; can be fried and baked (Ref. 9988).

Estimates based on models

Preferred temperature (Ref. 115969): 2.7 - 9.4, mean 4.5 (based on 270 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00111 - 0.00431), b=3.20 (3.03 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.56 se; based on food items.
