Short description Morfología | Morfometría

Espinas dorsales (total): 0; Radios blandos dorsales (total): 5-6; Espinas anales 0; Radios blandos anales: 5 - 6. Metamorphosed females distinguished by the following characteristics: length of illicium 340-447% SL; escal bulb with lightly pigmented truncated distal prolongation; 6-20 long distal filaments; escal papillae absent; proximal escal papillae absent; short dentary teeth (longest 1.3-3.4% SL, average 2.3% SL), arranged posteriorly in two longitudinal series; length of caudal fin rays less than 45% SL; weakly developed skin coverage of proximal part of caudal fin; caudal fin rays free nearly to base (Ref. 86949).

Appear to be active predators which feed on midwater fishes, including Cyclothone acclinidens, Triphoturus mexicanus and Bathylagus stilbius; cephalopods like Vampyroteuthis; and various invertebrates like amphipods, natant decapod crustaceans and coelenterates (Ref. 4525). Maximum length for female from Ref. 41361.

Estimates based on models

Preferred temperature (Ref. 123201): 2.4 - 5.6, mean 4.3 °C (based on 372 cells).

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

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.0 ±0.61 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
