Biology     Glossary (e.g. epibenthic)

A cryopelagic species associated with the underside of ice. An anti-freezing substance enable Individuals to tolerate sub-zero temperature (Ref. 33215). Adults feed on copepods and krill (Ref. 5179). Sexually mature individuals spawn once a year (Ref. 89319). Larval pelagic phase is long (Ref. 89319).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00332 - 0.01582), b=3.16 (2.97 - 3.35), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.34 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 1,500-3,000).
Vulnerability (Ref. 59153):  Moderate vulnerability (40 of 100) .
