The Sumatran tiger (Panthera tigris sumatrae) is a rare tiger subspecies that inhabits the Indonesian island of Sumatra. It was classified as critically endangered by IUCN in 2008 as the population was estimated at 441 to 679 individuals, with no subpopulation larger than 50 individuals and a declining trend. The Sumatran tiger is the only surviving member of the Sunda Islands group of tigers that included the now extinct Bali tiger (Panthera tigris balica) and Javan tiger (Panthera tigris sondaica). Sequences from complete mitochondrial genes of 34 tigers support the hypothesis that Sumatran tigers are diagnostically distinct from mainland populations.
