Demographic, Distribution, Habitat, Environment and Range:The Oceanic Whitetip is found globally in deep, open oceans, temperatures greater than 64 degrees F, and no colder than 59 degrees F. They typical temperature is between 6882 F. Most of the time, the Oceanic Whitetip is solitary, except when there is a large amount of prey present. [1], From 3 January 2013, the shark was fully protected in New Zealand territorial waters under the Wildlife Act 1953. This is how feeding frenzies occur.

They have also been implicated in numerous attacks on shipwreck survivors; especially during the second world war. Ventral surface dirty-white or cream. Second dorsal and anal fins often black-tipped. [1], It is found worldwide between 45N and 43S latitude. Interdorsal ridge indistinct or absent. [3] Recent studies show steeply declining populations because its large fins are highly valued as the chief ingredient of shark fin soup, and as with other shark species, the whitetip faces mounting fishing pressure throughout its range. An Oceanic Whitetip shark upper tooth measures between 18-23mm. To about 11.5 ft (3.5 m). Mating season is in early summer in the northwest Atlantic Ocean and southwest Indian Ocean, although females captured in the Pacific have been found with embryos year-round, suggesting a longer mating season there. However, research via longline capture data suggests that there is a correlation between population and distance. The sharks have become somewhat habituated so they often check out dive groups even if the divemasters have not brought anything to entice them with. The species epithet longimanus refers to the size of its pectoral fins (longimanus translates from Latin as "long hands").

[26] Little further population study occurred until 2003, when the numbers were estimated to have dropped by as much as 70% in the Northwest and Western Central Atlantic between 1992 and 2000. Oceanic whitetips are not fast swimmers, but they are capable of surprising bursts of speed. In the 1950s, fishery researchers in the Gulf of Mexico were surprised when they opened up the stomachs of whitetips and found five- and 10-pound tuna in them, because the sharks arent fast enough to chase down small tuna. If it is dead and floats, they will find it. 2020 Sharks and Rays. Its gestation period is one year. [7] Peter Benchley, author of Jaws, observed this shark swimming among pilot whales and eating their faeces. [2] However, its diet can be far more varied and less selectiveit is known to eat threadfins, stingrays, sea turtles, birds, gastropods, crustaceans, and mammalian carrion. The dives are conducted with a bait crate that attracts the sharks. Despite its habitual isolation from members of its own species, pilot fish, dolphinfish, and remora may accompany it. Upon associating the divers with an easy supply of food, it bit the divers and snorkelers on the areas of the body where it had seen the fish being kept, namely, in the fanny packs the divers carried.
