Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 33 - 35; Anal spines: 3 - 4; Anal soft rays: 30 - 33. Body grey, fins dark (Ref. 6548).

Biology     Glossary (e.g. epibenthic)

Inhabit continental slopes (Ref. 9563), forming large shoals over rough ground near pinnacles and canyons (Ref. 6390). Juveniles are pelagic and tend to be dispersed over smooth grounds (Ref. 6390). Feed on salps, fish, crustaceans and squid (Ref. 27230). Eggs float near the surface and larvae also inhabit surface waters (Ref. 6390).

Estimates based on models

Preferred temperature (Ref. 123201): 5 - 9.7, mean 7.8 °C (based on 131 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5635   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01698 (0.00988 - 0.02919), b=3.01 (2.85 - 3.17), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
