The Bengal tiger (Panthera tigris tigris) is the most numeroustiger subspecies. Its populations have been estimated at 1,706–1,909 in India, 440 in Bangladesh, 163–253 in Nepal and 67–81 inBhutan.[2][3][4][5] Since 2010, it has been classified as anendangered species by the IUCN. The total population is estimated at fewer than 2,500 individuals with a decreasing trend, and none of the Tiger Conservation Landscapes within the Bengal tiger's range is large enough to support an effective population size of 250 adult individuals.[1]
Bengal is traditionally fixed as the typical locality for the binomialPanthera tigris, to which the British taxonomist Pococksubordinated the Bengal tiger in 1929 under the trinomialPanthera tigris tigris.[6][7]
It is the national animal of both India and Bangladesh.[8]
