Biology     Glossary (e.g. epibenthic)

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).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00039 (0.00029 - 0.00052), b=3.26 (3.19 - 3.33), in cm Total Length, based on LWR estimates for this species (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):  Very high vulnerability (86 of 100) .
Price category (Ref. 80766):   Medium.
