Tigers are the largest class of felines in the world, but as of 2015, they are an endangered species with a population of only about 3,200 worldwide. A tiger's life span is typically between 14 to 18 years.
Each tiger's stripes are as distinct as a human fingerprint. Stripes help tigers camouflage themselves when they are hunting. Some tigers have orange and black fur; some are tan and black, and others are white. Tigers are typically between 4.8 and 9.5 feet long and weigh between 165 and 716 pounds. Siberian tigers can grow up to 10 feet long and are the largest breed; the Sumatran tiger is the smallest breed.
Tigers live in countries such as Asia, Russia, China, India and Nepal. They live in forests of various types depending on their subspecies and are talented swimmers. They are not highly social animals as they typically mark about 4,000 square miles of territory and travel it alone. A tiger's diet consists of pigs, deer, rhinos, elephant calves and other large prey.
A tiger's litter is as big as seven cubs, but only two typically survive due to the mother's hunting habits and inability to feed all of her cubs. Cubs begin to learn to hunt at eight weeks but do not venture away from their mothers until they are two years old.
