Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10 - 12; Anal spines: 0; Anal soft rays: 12 - 15; Vertebrae: 27 - 31. Branchiostegal rays: 9 (Ref. 31422). Anal organs 8; a single deeply set translucent supracaudal gland present in both sexes, but no infracaudal gland; males have much larger eyes and a longer supracaudal gland than those of females (Ref. 39633).

Biology     Glossary (e.g. epibenthic)

High-oceanic, epipelagic and mesopelagic (Ref. 4479). Found between 375-700 m during the day and between 25-350 m at night (Ref. 4066). Size stratification with depth during the day only (Ref. 4775). Juveniles migratory; adults migratory, partially migratory or non-migratory (Ref. 4775). Feed on copepods, conchoecid ostracods and euphausiids (Ref. 4775). Oviparous, with planktonic eggs and larvae (Ref. 31442). Also Ref. 58302.

Estimates based on models

Preferred temperature (Ref. 123201): 10 - 22.8, mean 15.2 °C (based on 1055 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [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   ±0.20 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=1; k >0.30).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
