Royal Bengal tiger


The Bengal tiger (Panthera tigris tigris) is the the common frequent tiger breed. Its populations have been probable at 1,706–1,909 in India, 440 in Bangladesh, 124–229 in Nepal and 67–81 in Bhutan. Since 2010, it has been confidential as an endangered species by the IUCN. The total populace is expected at lesser quantity than 2,500 persons with a diminishing trend, and none of the Tiger protection landscape inside the Bengal tiger's collected works is large enough to support an effective population size of 250 adult individuals.
Bengal is traditionally fixed as the typical locality for the binomial Panthera tigris, to which the British taxonomist Pocock subordinated the Bengal tiger in 1929 under the trinomial Panthera tigris tigris.
