生物學特性     字彙 (例如 epibenthic)

Some studies on feeding have shown that euphausiids comprised 46% by weight of the food consumed by this species. Spawning probably occurs 3-4 times a year (Ref. 5002).

在進食上的一些研究已經顯示磷蝦包含了被消費這種的食物的重量的 46% 。 一年 3-4 次可能產卵。 (參考文獻 5002)

Estimates based on models

Preferred temperature (Ref. 123201): -0.4 - 2.1, mean 0.6 °C (based on 593 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00205 - 0.01282), b=3.00 (2.79 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
