The Tiger Shark

Tiger shark, Galeocerdo Cuvier, is a Requiem shark species and the only member of the genus Galeocerdo. Generally known as sea tigers, tiger sharks are relatively large macropredator, can reach a length of more than 5 m (16 ft). It is found in many tropical and subtropical waters, and it is very common around central Pacific islands. Its name comes from the dark lines in the body that resembles a tiger pattern, which fade as the shark adult.

Tiger sharks are hunters, most solitary evenings. Diet includes a wide range of prey, from crustaceans, fish, seals, birds, squid, turtles, and sea snakes to a dolphin and small sharks and even the other. Tiger shark is considered to be near threatened species due to finning and fishing by humans.
While the tiger shark is considered to be one of the most dangerous sharks to humans, low-level attacks according to researchers. Tiger is the second in the list of recorded attacks on humans, with the first great white shark. They often visit shallow reefs, harbors and channels, creating a potential meeting with the man.

Tiger shark is often found close to the coast, especially in tropical and subtropical waters around the world. Along with the great white shark, Pacific sleeper shark, Greenland shark and sixgill shark, shark tiger shark is one of the largest remaining. Behavior, particularly nomadic, but is guided by warmer currents, and it remains close to the equator during winter. It tends to stay in deep waters that line reefs, but does not move to channel to pursue prey in shallow waters. In the western Pacific Ocean, sharks have been found as far south as far as northern Japan and New Zealand. A Tiger Shark marked in the Caribbean has been detected migrating Cape Cod, even though Tiger sharks are tropical species during the summer currents carry warm Gulf coast of Cape Cod to the north end of the range.

Tiger sharks can be seen in the Gulf of Mexico, North America and the coast of South America. It is well known in the Caribbean Sea. Other location where tiger sharks seemed to include Africa, People's Republic of China, Hong Kong, India, Australia and New Zealand.

Some tiger sharks have been recorded at depths just shy of 900 meters (3,000 feet), but some sources claim they move into shallow water is usually considered too shallow for the species size. A new survey shows the average tiger shark will go down to 350 meters (1,100 feet), so rare to see tiger sharks in shallow waters. However, tiger sharks in Hawaii have been observed at a depth of 10 ft and regular shallow coastal waters observed at a depth of 20 to 40 ft. They often visit shallow reefs, harbors and channels, creating the potential for encounter with humans.

Tiger shark known as Kiribati and Tuvalu Tababa on. They have been observed feeding on the intertidal flats of the lagoon and the sea in Tarawa, Kiribati. Spring tides bring plankton or animal self, which attracts small soft-shell crab, sardines interesting, attractive gray mullet, supported striking blue trevally (rereba), which then attract tiger sharks (Tababa).

One of the largest sharks living today, the tiger shark generally reach a length of 3 to 4.2 m (9.8 to 13.8 feet) and weighs around 385-635 kg (850 to 1.400 lb). Sometimes, very large tiger shark boy can grow up to 4.5 m (15 ft). Women are much larger, and very large reported can measure more than 5 m (16 ft). While the average smaller and, because shark sleek, slim build, usually less weight, the largest tiger shark great white to match the length. According to FishBase, tiger shark can grow up to 7.5 m (25 ft) long and 807.4 kg (1780 pounds) in weight. A Guinness World Records, one of the female specimens caught Australia reportedly measured 5.5 m (18 ft) long and weighing an incredible 1,524 kg (3360 pounds), although the estimated weight was decided by the pregnant at the time. A woman reported caught in 1957 measured 7.4 m (24 feet) and weighs 3,110 kg (6,900 lb), although this is very outsized unknown shark has been confirmed.
