Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7 - 9; Dorsal soft rays (total): 31 - 34; Anal spines: 0; Anal soft rays: 32 - 36. No swim bladder (Ref. 128162),

Found beyond 1,000 m depth. Both males and females often occur on the surface. In January and February, this fish is often found at a depth range of 300-500 m, in March and April, it is found between 100-120 m. Reproduction takes place in February until March. There are indications that the females perish after spawning. The larvae stay dispersed between the surface and 500 m; they do not undergo daily migrations (Ref. 2058).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Generation time: 4.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23; tmax=4).

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