Short description
Biology
Neustonic to mesopelagic (Ref. 58302). High-oceanic, nyctoepipelagic at the surface and down to 125 m. Found between 425-750 m during the day. Sexually mature from about 65 mm (Ref. 4479). Proximate analysis (excluding head) reveals that lipid content is 2.0 % in fresh body weight and wax ester is 17.2 % in total lipids (Ref. 9193).

Estimates based on models
Preferred temperature (Ref. 123201): 2.9 - 10.4, mean 6.6 °C (based on 1525 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00564 - 0.01857), b=3.25 (3.09 - 3.41), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278): 3.7 ±0.4 se; Based on food items.
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing vulnerability (Ref. 59153): Low vulnerability (10 of 100).
Nutrients (Ref. 124155): Calcium = 0 [0, 0] mg/100g; Iron = 0 [0, 0] mg/100g; Protein = 0 [0, 0] %; Omega3 = 0 [0, 0] g/100g; Selenium = 0 [0, 0] μg/100g; VitaminA = 0 [0, 0] μg/100g; Zinc = 0 [0, 0] mg/100g (wet weight);
