Benthopelagic and mesopelagic in slope and near continental and island waters (Ref. 9835, 11230). Found in 130-300 m during the day and in 10-200 m at night (Ref. 4066). Feeds in the evening (Ref. 9191). Feeds on mainly on copepods and various crustacean larvae. Lipid content is 4.6 % in fresh body weight (Ref. 8966).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00424 - 0.02467), b=3.10 (2.89 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.1 ±0.27 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (K=1.81).

Vulnerability (Ref. 59153): Low vulnerability (10 of 100) .

Price category (Ref. 80766): High.
