The Biggest Animals Kingdom | Tiger | The ancient remains of the tiger, like a cat, called Panthera palaeosinensis were found in China and Java. The earliest fossils of true tigers are known from Java, and between 1.6 and 1.8 million years. Subspecies called Trinil tiger (Panthera tigris trinilensis) lived about 1.2 million years ago and is known from fossils found at Trinil in Java. Tigers first reached India and northern Asia during the Pleistocene, reaching eastern Beringia (but not the Americas), Japan and Sakhalin. Fossils Japan show that local tigers were as subspecies island survivors, lower than the forms of the continent. Before the Holocene, tigers lived on the island of Borneo and the island of Palawan in the Philippines. Tigers have a muscular body, with a particularly powerful forelimbs and a large head. Model band is also in the skin of a tiger. If Tiger were shaved, its distinctive camouflage pattern can be saved.

Tiger is the most variable in size all the big cats, even more than the leopard, and more than lions. Bengal, Caspian Sea and Amur tiger subspecies are among the largest living cats, and are one of the largest cat that ever existed. An adult male tiger from northern India or Siberia, than the average male lion about 45 kg (99 pounds), women vary in length from 200 to 275 cm (79 to 108), weighing 65 167 kg (140,370 pounds), with a maximum length skulls 268-318 mm (10.6 to 12.5 cm). Large male Siberian tiger can reach a total length of 3.5 m (11.5 ft) "to curves", 3.3 m (10.8 ft) "between pegs" and weighing 306 kg (670 pounds). This is significantly larger than the size of the smallest of life reached the subspecies of tiger, Sumatran tigers, which reach a weight of 75 to 140 kg (170,310 pounds). The total length of the tail of the tiger is from 0.6 to 1.1 m (2.0 to 3.6 feet). In the shoulder, the Tigers could stand differently from 0.7 to 1.22 m (2.3 to 4.0 feet).

Tigress less than men in each subspecies, although the size difference between male and female tigers tends to be more pronounced in larger tiger subspecies, with males weighing up to 1.7 times more than women. In addition, male tigers have foot pads front wider than females. Biologists use this difference to determine the sex, based on a few tracks of a tiger. The skull is very similar to a tiger a lion, although the front area, as a rule, non-depressed or flat with a region slightly longer post-orbital. Only the large island inhabited by tigers today, Sumatra. Tigers have been eradicated on the island of Bali in 1940, around the Caspian Sea in 1970, and the island of Java in 1980.

Habitat loss and the constant killing of tigers and tiger prey precipitated these extirpations, a process that continues to leave forests devoid of tigers and other large mammals in South and Southeast Asia.  Fossils show that the Tigers were presented at the Borneo and Palawan in the Philippines in the late Pleistocene and Holocene. The tiger habitat is generally include adequate coverage, proximity to water, and abundance of prey. Bengal tigers live in many types of forests, including wet green, semi-evergreen of Assam and West Bengal, the mangrove forests in the delta of the Ganges, deciduous forest and thorn forests of Nepal Western Ghats. In the wild, tigers mostly feed on animals large and medium sized businesses. Sambar, gaur, chital, barasingha, wild boar, nilgai, and both the domestic buffalo and buffalo, favored victim of a tiger in India.

In Siberia, the main types are the victims of the Manchurian deer, wild boar, spotted deer, elk, deer and musk deer. In Sumatra, sambar, muntjac, wild boar, and Malayan tapir hunt. In between the first Caspian tiger, prey included Saiga antelope, camels, Caucasian bison, yak and wild horses. Adult elephants are too big to be a common prey, but conflicts between tigers and elephants also occasionally occur. The case where a tiger killed an adult Indian rhino is not observed. Tigers also sometimes attack pets such as dogs, cows, horses and donkeys. 

Tigers old or injured and are unable to capture their natural prey have become cannibals, this pattern is repeated many times throughout India. Exceptional case is that the Sundarbans, where healthy tigers prey upon fishermen and farmers in search of forest products, people, forming a small part of the diet of the tiger. Tiger will have some vegetation in dietary fiber, fruit of the tree slowly while playing a game Tigers are thought to be nocturnal predators hunt at night. When hunting large prey, tigers prefer to bite the throat and use their forepaws to hold the prey, bringing it to the ground. Tiger is still locked around his neck until the victim dies of asphyxiation. With this method, water buffalo and gaurs weighing more than a tonne have been killed by tigers more weighing approximately one-sixth.

With small prey, the tiger bites the nape, often breaking the spinal cord enters the trachea, or splitting the jugular vein or carotid artery. Litter usually consists of 3-4 cubs of about 1 kg (2.2 pounds) each, which are born blind and helpless.  Females reach sexual maturity at 3-4 years, while males reach sexual maturity in 4-5 years. During his lifetime, a woman will give birth to an equal number of tiger cubs males and females. Tigers reproduce well in captivity, captive, and the population in the United States can compete with wild populations of the world.
