Short description Identification keys | 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. Dorsal and anal fins terminate just a little on the blind side of the caudal peduncle. Lateral line forms a distinct curve above the pectoral fin. Dorsal and anal fin with indefinite darker spots posteriorly.

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

Estimates based on models

Preferred temperature (Ref. 115969): 6.3 - 11.4, mean 7.7 (based on 165 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7520 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00479 (0.00375 - 0.00610), b=3.10 (3.03 - 3.17), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.1 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.13; tm=2-4; Fec = 26,522; tmax=16).

Prior r = 0.41, 95% CL = 0.27 - 0.62, Based on 9 full stock assessments.

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).

Climate Vulnerability (Ref. 125649): Low vulnerability (25 of 100).

Price category (Ref. 80766): Very high.
