Tiger Shark (Galeocerdo cuvier)
Tiger Sharks are found in the warm waters of tropical and temperate regions, spending most of their time within murky coastal waters in search of available food sources. It has been noted that young Tiger Sharks tend to feed on various species of fish as well as sea snakes, but as they grow are more likely to feed on sea birds, Dugongs (Dugong dugon), and even sea turtles (Chelonioidea). Though lethal shark attacks are rare, Tiger Sharks are regarded as the most dangerous shark species to humans, because they hold the highest percentage of lethal attacks to humans compared to any other shark. This is mainly do to the fact that they often congregate in shallow waters and harbors, and typically attack once bumped or threatened.
Galeocerda cuvier is the largest known shark species, growing up to 20-25 feet (6 to 7.5 meters) in length with an average weight of about 1,900 lbs (900 kg). These sharks have blunt noses, and during their youth, are covered in dark vertical stripes. As they mature, these stripes typically fade.
Tiger Sharks are harvested for their fins, skin, and livers (which contain high amounts of Vitamin A used for the manufacturing of vitamin oil). These sharks also have low population rates. Both of these factors have unfortunately contributed to a decline in Tiger Shark numbers. They are now listed as near-threatened throughout the world.
