Biology     Glossary (e.g. epibenthic)

Oceanic (Ref. 4066). Found in the upper 50-100 m south of Antarctic Polar Front at night, but deeper (500-600 m) north of Antarctic Polar Front and at depths greater than 1,000 m at Subtropical Convergence. Feeds mainly on copepods, and also on euphausiids and amphipods.

Estimates based on models

Preferred temperature (Ref. 123201): 0.4 - 7.5, mean 3.1 °C (based on 444 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00297 - 0.01609), b=3.13 (2.93 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.19 se; based on food items.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
