Biology     Glossary (e.g. epibenthic)

Epi-, meso-, and perhaps bathypelagic at 1->400 m (Ref. 58302 ). Occurs at or near the surface at night, descending to below 400 m (possibly as deep as 1,800 m) during the day (Ref. 31367 ). Feeds on squid, bony fishes, and crustaceans (Ref. 5578 ). Ovoviviparous (Ref. 205 ), with 8 young per litter, size at birth between 6 and 10 cm (Ref. 247 ). Caught with dip-nets and buckets at night (Ref. 6577 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Ovoviviparous, with 8 young per litter. Size at birth between 6 and 10 cm (Ref. 247 ). Distinct pairing with embrace (Ref. 205 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 5.7 - 15.3, mean 9.2 °C (based on 870 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 1.0020   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00372 (0.00141 - 0.00976), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.1   ±0.4 se; based on diet studies. Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (Fec=8). Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (21 of 100).
