Tiger Shark

True Wild Life | Tiger Shark | The tiger shark is the fourth biggest shark in the world and is found in warmer and tropical waters in the Southern Hemisphere. The tiger shark tends to be found in more coastal waters but tigers sharks are also known to go into the deeper ocean if they need to hunt for food. The tiger shark is a fierce predator and tiger sharks hunt everything in the water including fish, seals, birds, turtles and even other sharks. The tiger shark gets it's name from the black stripes it has when it is young. Most tiger sharks lose these stripes as they get older.

Like most other species of shark, tiger sharks have sensors on the sides of their heads which enable them to detect small muscle movements from nearby creatures. The tiger shark also has a wedge-shaped head which allows the shark to turn quickly when it needs to. Tiger sharks can reach a top speed of around 20mph which is pretty fast in the water! Tiger sharks are extremely aggressive animals are thought to be one of the most dangerous sharks for humans to come into contact with. Tiger sharks are solitary hunters and usually do most of their hunting at night when the tiger shark can move through the water unseen.

Female tiger sharks mate every three years or so and the time of year when this happens depends on where the tiger shark lives. Tiger sharks in the Northern Hemisphere mate from March to May, where tiger sharks in the Southern Hemisphere mate from November to January. The eggs hatch inside the female tiger shark and can remain inside her for up to 16 months. When they are big enough, the female tiger shark gives birth to between 10 and 80 baby tiger sharks.

Tiger sharks usually range from between 3 to 5 metres in length. Although much larger specimens have been seen, the largest a tiger shark tends to get is around 5.5 metres long.

Tiger Salamander

True Wild Life | Tiger Salamander | The tiger salamander is a small species of salamander, found inhabiting wetland habitats across North America. The tiger salamander can be easily distinguished from other species of salamander by the dark-coloured markings on the skin of the tiger salamander. An adult tiger salamander is rarely seen out in the open as they spend their lives in burrows about half a meter into the ground. Most adult tiger salamanders live in their burrows on the land, only returning to the water to mate.

The tiger salamander is green, black, brown or grey in colour and has blotchy markings on its skin. The tiger salamander also has sturdy legs and a long tail, all of which the tiger salamander is able to regrow should these limbs become lost or damaged. The tiger salamander is a carnivorous amphibian mainly hunting worms, insects and spiders that crawl into its burrow. Adult tiger salamanders are also known to hunt much larger animals such as baby mice and small frogs.

Due to the small size and ground-dwelling nature of the tiger salamander, the tiger salamander has numerous natural predators where it lives in North America. Raccoons, coatis and river turtles are the most common predators of the tiger salamander, along with birds and large reptiles. Most tiger salamander individuals will only get the chance to breed just once in their up to 15 years lifetime. The larvae of the tiger salamander are aquatic which means that the female tiger salamander lays her eggs in the water, generally on either a log or leaves close to the bottom of the water.

The eggs of the tiger salamander hatch into larvae which come in two forms, cannibalistic (meaning that they eat one another ) and non-cannibalistic larvae. The larvae take a varied amount of time depending on the region, to fully metamorphose into an adult tiger salamander.

Tiger

True Wild Life | Tiger | The tiger is the largest feline in the world, with the tiger growing to around 2.5 metres in length. The tiger is the most powerful of all the big cats, and is native to east and southern Asia. The tiger is feared by most human beings who inhabit settlements within the tiger's territory. There are six different subspecies of tiger which are the Bengal tiger, the Indochinese tiger, the Malayan tiger, the Sumatran tiger, the Siberian tiger and the South China Tiger. The white tiger is actually a Bengal tiger and is therefore not a subspecies itself.

The average tiger weighs around 300kg and a tiger can stretch its body (and tail) to roughly 4 metres. Tigers hunt snakes, boar, buffalo, crocodiles, deer, leopards and camels and are extremely effective at catching their prey due to their silent, stalking approach and their powerful bodies. The tiger can reach speeds of up to 90km an hour, making the tiger extremely fast. Tigers have even been known to conflict with rhinos and elephants with the tiger generally winning.

Tigers are generally orange with black stripes although it's common to get tigers with white and sandy coloured markings. The white tiger is a rare type of tiger, with bright white fur and black stripes, these tigers occur from a genetic mutation when in the mother tiger's womb. It is not certain that these white tigers will produce white offspring, many white tigers have been known to produce orange cubs. Today the tiger is a near endangered species with only a handful still roaming the Asian jungles. The tiger is still a completely dominant predator in it's environment particularly due to their extreme power, and ability to run, swim, jump and climb trees very effectively.

The tiger is a highly adaptable animal with the tiger's territory ranging from Siberia, to open grasslands and tropical mangrove swamps in central and south-east Asia. The tiger is also an extremely territorial animal and the tiger is generally a solitary animal. Due to the tiger's size and the tiger's want to be solitary, the tiger often requires large areas of habitat that can support the tiger's prey demands. Because of the tiger's need for a large territory mixed with the fact that the tiger is native to some of the more densely populated places on earth, has meant that there have been significant conflicts between tigers and humans.

Tigers usually mate from November to April and after a gestation period of just over 3 months, the female tiger gives birth to 2 or 3 tiger cubs. When the tiger cubs are first born they are blind and extremely vulnerable. By the time the tiger cubs is around 18 months old, it is able to hunt for itself. Tiger cubs are known to grow rapidly and can put on 100 g of weight every day. The tiger cubs usually stay with their mother until they are between 2 and 3 years old and the tiger cubs are then big enough and strong enough to venture out into the jungle to live a life of solitude.
