The Tiger (aka Panthera Tigris) is the largest member of the felidae family and is one of the four big cats in the Panthera genus. The tiger as a whole is an endangered species, with the majority of the world's tigers now living in captivity. Several subspecies are extinct and others critically endangered and their historical range has declined by 90 percent compared to a century ago. The tiger used to roam throughout Asia, as north as Siberia in Russia, as west as Turkey, and as South as Sumatra. Unfortunately, three out of the nine subspecies of tigers have gone extinct. All surviving tiger subspecies are highly endangered while the China Tiger, aka the South China Tiger which is the most ancient tiger on the planet, is on the verge of extinction.
