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).
