Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; demersal; depth range 50 - 848 m (Ref. 56504), usually ? - 150 m (Ref. 10780). Deep-water; 52°N - 15°S, 18°W - 36°E

Eastern Atlantic: British Isles and English Channel to Angola, including the Mediterranean.

Length at first maturity / Size / Weight / Age

Maturity: L_m ?, range 22 - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 3397); common length : 18.0 cm TL male/unsexed; (Ref. 3397)

Depth range from 50-600 m (Ref. 10780) and from 288-848 m in the eastern Ionian Sea (Ref. 56504). Gregarious. Occurs on muddy or rocky bottoms of the shelf. Digs the mud with its rostrum, searching for prey; stands and walks on the bottom with its free pectoral rays. After a pelagic existence, the juveniles live in coastal waters before migrating to deeper waters (Ref. 6556). Minimum depth range taken from Ref. 27000.

Estimates based on models

Preferred temperature (Ref. 123201): 8 - 17.4, mean 13.8 °C (based on 488 cells).

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

Bayesian length-weight: a=0.00457 (0.00308 - 0.00678), b=3.01 (2.89 - 3.13), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.3 se; based on size and trophs of closest relatives

Generation time: 6.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 33.8 [16.2, 73.9] mg/100g ; Iron = 0.379 [0.222, 0.663] mg/100g ; Protein = 17.1 [15.7, 18.5] % ; Omega3 = 0.479 [0.216, 1.317] g/100g ; Selenium = 23.8 [10.4, 53.2] μg/100g ; VitaminA = 10.5 [3.0, 36.7] μg/100g ; Zinc = 0.456 [0.317, 0.665] mg/100g (wet weight);
