Bengal Tiger
The Bengal tiger, which is often referred to as the "Indian tiger," is the most common of all tigers, according to the National Geographic.
Despite that, Bengal tigers are an endangered species. With regard to possible extinction, the most prominent issues that Bengal tigers face are both unlawful poaching and minimization of their natural habitat, the latter usually from deforestation or agricultural activities. As for illicit poaching, their bones are believed by some to provide useful health benefits (used specially in china medicines).
