Short description Morphology | Morphometrics

Dorsal soft rays (total): 16-17; Anal soft rays: 13; Vertebrae: 50 - 51. Moderately elongate and slender. Slightly depressed anteriorly and compressed posteriorly. Color generally white, with peritoneum, branchial and buccal regions dark. Small specimens have faint vertical bars (Ref. 37039).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Circumglobal between latitude 50°N-20°S except tropical eastern Pacific. Eastern Atlantic: northern Ireland; Morocco to Gabon.

Benthic (Ref. 58302). Found on the continental rise and the abyss, commonly below 2,000 m, in water colder than 4°C. Larvae are probably pelagic in near-surface midwaters. Solitary, lurking bottom feeder. Probably piscivore (Ref. 4964).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (-0.30300 - 0.32300), b=3.04000 (2.92100 - 3.15900), based on all LWR estimates for this BS (Ref. 93245).

Trophic Level (Ref. 69278): 4.5 ±0.80 se; Based on food items.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).

Vulnerability (Ref. 59153): Moderate to high vulnerability (51 of 100) .

Price category (Ref. 80766): Medium.
