Oceanic and non-vertical migrant (Ref. 4739). Mesopelagic at 275-1200 m (Ref. 58302). Commonly found in 500-800 m both day and night (Ref. 4054). Possibly a cyclic feeder of copepods, ostracods, euphausiids, amphipods, fishes and other taxa (Ref. 4739). Adult photophore complement acquired at 11-13 mm SL (Ref. 4739). Lipid content 1.4 % in fresh body weight and wax ester is 4.2 % in total lipids (Ref. 9193).

Estimates based on models

Preferred temperature (Ref. 115969): 2.4 - 10.4, mean 6.8 (based on 1057 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.03467 (0.02139 - 0.05620), b=2.96 (2.82 - 3.10), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.2 se; based on diet studies.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Assuming tmax>3).

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