Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 10 - 11; Épines anales: 0; Rayons mous anaux: 19 - 21. Olive brown in color, edges of scale pockets blackish; 2 black bands formed by peritoneum showing through body wall; blackish triangular spot on caudal base (Ref. 6602).

Biologie     Glossaire (ex. epibenthic)

Mesopelagic to bathypelagic (Ref. 6602). Sometimes taken at depths greater than 500 m (Ref. 6602). Feeds on smaller plankton, mainly copepods. Hermaphrodite, spawning probably occurs in the North Atlantic in a belt stretching across the ocean in subtropical latitudes. Specimens approaching sexual maturity lose their teeth and gillrakers completely (Ref. 6689) suggesting semelparity (RF).

Estimates based on models

Preferred temperature (Ref. 123201): 5.5 - 15, mean 9.1 °C (based on 1365 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00288 (0.00120 - 0.00692), b=3.18 (2.96 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.0   ±0.00 se; based on food items.
Résilience (Ref. 120179):  Faible, temps minimum de doublement de population : 4,5 à 14 années (Assuming semelparity and tm>5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (23 of 100).
