Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 85-94; Anal soft rays: 64 - 74. Dorsal fin origin closer to tip of snout than to anterior edge of eye.

Biology     Glossary (e.g. epibenthic)

Occurs on soft bottoms. Depth range from 100-400 m (Ref. 06302) and from 288-700 m in the eastern Ionian Sea (Ref. 56504). Feeds on small bottom-living fishes as well as on squids and crustaceans (Ref. 4703). Spawns in deep waters off Iceland and west of the British Isles (Ref. 35388).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7520   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00322 - 0.00816), b=3.08 (2.94 - 3.22), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.8 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.13; tm=3-4).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100) .
Price category (Ref. 80766):   Very high.
