Ecology of Histioteuthis bonnellii

Main Ref.	Roper, C.F.E., M.J. Sweeney and C.E. Nauen, 1984
Remarks	Oceanic and elusive. Has little interaction with the bottom (Ref. 106095). Mainly feeds on osteichthyes, followed by crustaceans (natantian), and occasionally on cephalopods. Bases their diet on pelagic nictemeral migrators (Ref. 106992).
