Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 14 - 17; Anal spines: 0; Anal soft rays: 12 - 16. Black in color, pale luminous patches on middle of snout and along front of upper jaw (Ref. 3982). Pale luminous patches develop with growth on shoulder and on lower sides between pectoral and pelvic fins below dorsal (Ref. 3982). Body moderately elongate and slender, maxillary teeth comblike. Serial photophores are not broken into small groups (Ref. 37039).

An oceanic and mesopelagic species usually found deeper than 500 m during the day. Feeds on midwater fishes and crustaceans. Most common species taken in surface nets at night (Ref. 2802).

Estimates based on models

Preferred temperature (Ref. 123201): 9.2 - 20.6, mean 14.2 °C (based on 612 cells).

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

Bayesian length-weight: a=0.00417 (0.00171 - 0.01014), b=3.05 (2.84 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.62 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).

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