Fun Facts About Tiger Sharks Biography

Tiger Sharks are considered the second most dangerous shark for humans, second only to the Great White Shark. But as with all species, attack rates are quite minimal.

Tiger Shark Facts
Also known as the Galeocerdo Cuvier, this is a species of requiem shark - a family of sharks who prefer warmer waters, among other things.
It got its name from the tiger like stripes on the juveniles. These stripes are only present in adolescents. As they mature, the stripes disappear. By the time they get to adulthood, about 3 meters (10 feet) long, the stripes may not even be visible anymore.
This is one of the largest species of sharks. Many grow to more than 4 meters (13 feet) and weigh 400 to 700 kilograms (880 to 1,500 pounds). Yet, most experts believe there are some very large "giants" out there weighing more than 3 metric tons (over 6,500 pounds) with a length of over 7 meters (23 feet)!
While they typically only live 15 to 20 years, some can grow and live 40 to 50 years.

Habitat
This fish loves the tropical waters all over the world. They seem to concentrate around Melanesia, Micronesia, and Polynesia. They prefer deep water with a depth of about 800 meters (2,600 feet). The Tiger Shark usually must move to shallow water in order to hunt its prey.

Sensory System
Like all other sharks, they have a special electro receptors called Ampullae of Lorenzini. This allows them to track their pray from motion and electric impulse that living creatures naturally give off.
In addition, they have a sensory organ named Later Line that extends of the flanks and stretches over the entire body. With the Lateral Line, they can feel very small vibrations in the water which makes them excellent hunters in the dark.
Social Behavior

For the most part, these sharks are nomads traversing the Ocean. They wander around in tropical waters in search of warmer currents. Often, they are found in large groups for collective hunting and mating. Experts have found that they have a pronounced social structure, especially during mating.

Hunting Behavior
Their teeth are considered "cutters" meaning they can slice through flesh, bones, and even turtle shells. They are known for eating everything that comes in contact with their mouths. They will even eat garbage. That earned them the nickname "wastebaskets of the sea." But their preferred preys are fish, dugongs, species of dolphins, seabirds, and seaturtles. This species is a very fast swimmer and they tend to use that to their advantage when hunting.

Offspring
Similar to the Great White Shark, the Tiger Shark is ovoviviparous. That means eggs evolve in the uterus of a female until birth. The pregnancy period lasts about 1 year and they give birth to many pups at once, typically between 20 and 90. Baby sharks are usually between 60cm and 100cm (2 to 3ft) at birth.
Relationship with Humans
Unfortunately, Tiger Sharks and humans haven't been great friends. While attacks on humans are rare, humans attacking the sharks has been all too common. This species is typically captured for its fins, shark oil, liver, tails, and flesh. Due to the rapidly declining population, protective laws are being enacted.
