Whitetip sharks are inhabitants of the open ocean. They never stop swimming. Normally solitary, they will gather together in the presence of large quantities of food to form feeding frenzies. Oceanic whitetips are often described as stubborn. They are inquisitive and have little fear of people. They are known to attack humans, and would undoubtedly be responsibel for many more attacks except that their habits place them far out to sea, where people seldom venture except in boats. Shipwrecked sailors are their most frequent victims, the crew of the U.S.S. Indianapolis, torpedoed by the Japanese in WWII, was likely primarily eaten by oceanic whitetips.
