Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2 - 3; Dorsal soft rays (total): 10 - 12; Anal spines: 1; Anal soft rays: 9 - 10; Vertebrae: 27 - 30. Branchiostegal rays: 8 (Ref. 36655). Large eye, measures more than 20% of head length. Body slender and angular. Scales on body and operculum mostly missing. Pelvic fin long, extends almost to anal fin origin. Gal bladder well developed (Ref. 37108).

Mesopelagic species, adults trawled at depths below 400 m, juveniles below 150 meters. There is significant morphological variation between Indo-Pacific and other populations. Oviparous, with planktonic eggs and larvae (Ref. 36655).

Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 11.5, mean 7 °C (based on 293 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

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