Morphology | Morphometrics
Mesopelagic at 300-900 m (Ref. 58302). Young migrate in association with Cyclothone signata to within 200 m of the surface at night and feed extensively on small crustaceans (Ref. 4525). Oviparous, with large mesopelagic larvae (Ref. 35760).

Estimates based on models
Preferred temperature (Ref. 115969
): 0.5 - 7.9, mean 3.5 °C (based on 290 cells).
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.30 se; based on food items.
Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Vulnerability (Ref. 59153
): Low vulnerability (19 of 100) .
