Oceanic whitetip shark (Carcharhinus longimanus):
Oceanic whitetip sharks are one of the few shark species that you must exercise extreme caution around. This shark's large rounded dorsal fin and very long pectoral fins distinguish it from other sharks. The tips of all these fins are whitish in color - markings that give the whitetip its name. Oceanic whitetips average less than 3m in size with a maximum age of 22 years.  While oceanic whitetips are found well offshore in the open ocean, they are very bold and unpredictable, especially around potential prey.  Oceanic whitetip sharks are the first to appear on the scene of a diaster and often exhibit feeding frenzy behavior.  They aren't very selective in their food choices eating bony fish, sting rays, sea turtles, sea birds, dead whales, and even garbage.  One of their main feeding strategies involves swimming into a group of fish with their mouths wide open.  Oceanic whitetips can also "sniff the air" for prey by tasting the water.  Since oceanic whitetips are found all over the world, they are subject to pressure from many fisheries. Oceanic whitetip sharks are often caught as bycatch with tuna and other commercially-sought open ocean fish species. Fishermen target oceanic whitetips for their meat, leather, liver oil, and especially their prized fins.  As a result the oceanic whitetip shark is listed as "vulnerable" on the International Union for Conservation of Nature's "Red List" of threatened species.
