Interspecific competition between the great white shark and the orca is probable in regions where dietary preferences of both species may overlap.[127] An incident was documented on 4 October 1997, in the Farallon Islands off California in the United States. An estimated 4.7–5.3 m (15–17 ft) female orca immobilized an estimated 3–4 m (9.8–13.1 ft) great white shark.[149] The orca held the shark upside down to induce tonic immobility and kept the shark still for fifteen minutes, causing it to suffocate. The orca then proceeded to eat the dead shark's liver.[127][149][150] It is believed that the scent of the slain shark's carcass caused all the great whites in the region to flee, forfeiting an opportunity for a great seasonal feed. Another similar attack apparently occurred there in 2000, but its outcome is not clear.[151] After both attacks, the local population of about 100 great whites vanished.[150][151] Following the 2000 incident, a great white with a satellite tag was found to have immediately submerged to a depth of 500 m (1,600 ft) and swum to Hawaii.[151]
