  1. Oceanic WhitetipShark(Carcharhinuslongimanus) By: Sam Kraybill and Troy Fort

  2. Geographical Range • I prefer deep ocean water of about 18 degrees. • Lies mainly between 45° N and 43° S latitude. • I spend most of my time in water of about 150 meters.

  3. Physical Traits • Long, wing like pectoral fins make me very recognizable. • Color varies from brown to yellow to bronze depending on my geographical region. • I grow to around 10 feet in length and about 370 lbs. Females are usually about 4 inches longer than males. • My upper jaw contains broad, triangular, serrated teeth, while the bottoms are only serrated at the tip. • I have nictitating membranes which are eyelids which close to protect its eyes when biting.

  4. Diet and Feeding Habits • I feed on bony fish such as: lancetfish, oarfish, barracuda, dolphinfish, marlin and tuna. • I also eats stingrays, sea turtles, sea birds, gastropods, crustaceans and mammalian carrion. • You can tell by my diet that the whitetip shark has evolved to eat whatever comes its way because it has no room to be a picky eater way out in the center of the ocean. • I find my prey using the sensitive area at the snout of the shark called the ampullae of Lorenziniwhich contain small jelly-filled sacs sensitive to small electrical impulses.

  6. Predators • Larger sharks pose a major danger to adolescent whitetips.

  7. Survival of the Oceanic Whitetip • My number one threat is humans. • Sharks have long meaty fins that make it an excellent choice for fishermen to catch for sharkfin soup, a delicacy in certain Asian countries. • The fishermen catch the adults at such a high rate that the species doesn’t have enough time to repopulate. • Because of this, the species is vulnerable to extinction.

  8. Reproduction • Mating takes place in the early summer in the NW Atlantic Ocean and SW Indian Ocean. • Interestingly, the female sharks like me are viviparous meaning that the eggs hatch inside of the mother and are then born alive. • Year long gestation period. • Usually gives birth to 1-15 pups.

  9. Behavior • My relationship with the Shortfin Pilot whale make me interesting • In Hawaii I follow the Pilot Whales when they dive so that I may more easily feed on the squid with the whales. • I am typically solitary and move slowly. • Except when ships come around I’ve been known to follow them for vast distances.

  10. Fun Facts • A famed oceanographer named Jacques Cousteau called me the most dangerous shark in the ocean. • I am accredited with the most casualties towards humans. • During WWII when the USS Indianapolis was sank by a German submarine I was thought to have caused the deaths of approximately ¼ of those who survived the initial sinking.
