An oceanic and mesopelagic species concentrated at 300-600 m by day and 100-300 by night (Refs. 4462, 4739). A selective dusk-time feeder mainly on conchoecid ostracods, to lesser extent on copepods, decapod larvae, fish larvae, etc (Ref. 4739). Adult photophore developing at about 15 mm SL (Ref. 4739).

Estimates based on models

Preferred temperature (Ref. 123201): 4.9 - 13.7, mean 8 °C (based on 1129 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.01297 - 0.04045), b=2.99 (2.84 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.2 se; based on diet studies.

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

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