Indian TigerClass: Mammalia
Order: Carnivora
Family: Felidae
Genus species: Panthera, Tigris
Size: The size of a male tiger can range up to 3 m and the female to 2.7 m.
Weight: The weight of a male can be up to 225 kg female to 135 kg largest existing member of the cat family.
Sexual maturity: Females attain sexual maturity at 3 to 4 years whereas males achieve the same at the age of 4 to 5 years.
Tigers are the biggest cats in the world and India is the home to two thirds of the world’s inhabitants of tigers. Over the past century the amount of tigers in India has fallen from about 40,000 to a smaller amount than 4,000. inexorable poach and clearing of habitat for agriculture have been the most important drivers of this take a rain check, though demand for tiger skins and parts for "medicinal" purpose has be converted into an all the time more important threat in recent years.
In the present day, there are about 2,500 of the Indian Royal Bengal tigers left and also there are 1,000 Indo-Chinese tigers, 300 Sumatran tigers, 300 Siberian tigers and 20 South China tigers.
As a result, the Indian tigers give the impression to be the most to be expected to survive in the future. On the other hand, it will even be easier said than done for them, and their chance of continued continuation strength is moderately low. If this rate of death is permissible to carry on, all species of tigers all the way through the world will be wiped out by 2010.
