According to the World Wildlife Fund, as of 2014, approximately 3,200 tigers live in the wild in 13 Asian countries. In the early 20th century, before hunting and habitat loss led to the extreme decrease in numbers, it is estimated that there were over 100,000 tigers in the world.
The largest species of big cat is the Siberian tiger living in eastern Russia's birch forests with a minor presence in China and North Korea. Tigers are solitary animals that use their scent to mark territory and roam many miles in search of prey. The coat of a tiger is unique and is used as camouflage in the jungle habitat.
