Tigers are classified as endangered by the International Union for Conservation of Nature and Natural Resources, a global organization that researches wildlife populations and grants endangered status. As of 2010, there are approximately 3,000 tigers left in the wild.
Tigers are divided up into several subspecies, of which the Bengal tiger is perhaps the most well known. Most subspecies have about 500 individuals remaining in the wild, with some having so few that they are considered functionally extinct. The biggest threat to tigers is trade in their skins and other body parts. Tigers are hunted for their distinctly patterned fur and for various body parts that are processed and used in traditional Chinese remedies. They also face habitat loss from human populations spreading into their range and are subject to hunting by farmers defending their livestock.
