Remarks 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.
