Biology     Glossary (e.g. epibenthic)

Mesopelagic (Ref. 58302). Exhibit diel vertical migrations, juveniles and adults mainly at 300-600 by day and at 50-200 by night (Ref. 4463, 58302). Feed on copepods and euphausiids (Ref. 4769).

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00389 (0.00170 - 0.00889), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		3.0   ±0.13 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 (17 of 100). 🛈
