Morphology | Morphometrics
High-oceanic and bathypelagic (Ref. 6604). Adults usually found below about 1,000 m, but juveniles found between 500-800 m. No evidence of vertical migration (Ref. 6604). Feed mainly on small crustaceans. Sexually mature from about 15.2 cm (Ref. 4525). Oviparous, with planktonic larvae (Ref. 36062).

Estimates based on models
Preferred temperature (Ref. 123201
): 4.2 - 7.7, mean 5.7 °C (based on 645 cells).
Phylogenetic diversity index (Ref. 82804
= 0.7656 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00363 - 0.02397), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.30 se; based on food items.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100).
