Marine; demersal; oceanodromous (Ref. 51243); depth range 0 - 1171 m (Ref. 56504). Temperate, preferred 15°C (Ref. 107945); 68°N - 12°N, 32°W - 42°E
Eastern Atlantic: Norway and Iceland to Senegal. Also in the Mediterranean and Black Sea.
Length at first maturity / Size / Weight / Age
Maturity: Lm 200.0  range ? - ? cm
Max length : 300 cm TL male/unsexed; (Ref. 4453); common length : 100.0 cm TL male/unsexed; (Ref. 4645); common length :150 cm TL (female); max. published weight: 110.0 kg (Ref. 35388)
Found on rocky and sandy bottoms (Ref. 12382). Depth range from 0-500 m (Ref. 4453) and from 305-1171 m in the eastern Ionian Sea (Ref. 56504). It stays near the coast when young and moves toward deeper waters upon reaching adulthood (Ref. 5377). A nocturnal (Ref. 12382) predator of fish, crustaceans, and cephalopods (Ref. 6521). Like other species of the group, it reproduces only once in its life (Ref. 5377). Sexually mature at an age of 5-15 years. Spawn in summer in the Atlantic off Portugal and in the Mediterranean. Produces 3-8 million of eggs (Ref. 35388). Marketed fresh and frozen. Eaten fried and baked (Ref. 9988).
Eggs are deposited in the open sea, at depths between 2,000 and 3,000 m (Ref. 12382).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00046 (0.00027 - 0.00076), b=3.20 (3.05 - 3.35), based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic Level (Ref. 69278
): 4.3 ±0.4 se; Based on diet studies.
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (K=0.06; tm=5-15 (female tm>10); Fec=3,000,000).
Prior r = 0.27, 2 SD range = 0.16 - 0.46, log(r) = -1.31, SD log(r) = 0.27, Based on: 2 K, 2 tgen, 2 Fec records
Vulnerability (Ref. 59153
