Ecology Summary - Carcharhinus falciformis

اللغة:

المرجع الرئيسي	Compagno, L.J.V., 1984
ملاحظات	Viviparous. Fish is main food source but occasionally eats cephalopods and pelagic crustaceans (Ref. 127989). Often found over deepwater reefs and near insular slopes. When approached by divers, individuals have been seen to perform a 'hunch display', with back arched, head raised and caudal fin lowered, possibly as a defensive threat display. Associated with schools of tuna, causing damage to nets and catches. Referred to as the `net-eater shark' in the tropical eastern Pacific. Also in Ref. 9137.
