Main Ref.	Tan, J.M.L., 1995
Remarks	Found in deep offshore areas (Ref. 936, 122680). Their main foraging grounds are those with high density of squid (Ref. 122680), its primary food. Sometimes feeds on fish (Refs. 936, 122680) and octopus (Ref. 122680). They are gregarious, rarely found solitary (Ref. 114960). Forms groups but hunts individually when feeding (Ref. 130961).
