Ecology of Todarodes sagittatus

Main Ref.	Schneider, W., 1990
Remarks	Demersal, neritic (Ref. 112172). Occurs from the surface to a depth of 2500 m (Ref. 2614). Juveniles feed mainly on fishes while adults consume crustaceans (Ref. 112351). Migrates to offshore waters during winter; spawning is thought to occur in the continental slope (Ref. 2614).
