It was listed as Critically Endangered on the IUCN Red List in 2008, with no subpopulation larger than 50 individuals and a tiger habitat map trend. As the population was estimated at 441 to 679 individuals, the Sumatran tiger is the only surviving population of the Sunda Islands’ group of tigers that included the now extinct Bali and Javan tigers. Pocock first described the Sumatran tiger on the basis of several skull, sequences from complete mitochondrial genes of 34 tigers support the hypothesis that Sumatran tigers are diagnostically distinct from mainland subspecies. The Cat Classification Task Force of the Cat Specialist Group revised felid taxonomy and now recognizes the tiger living and extinct tiger populations in Indonesia as P.
And striping features, which are distinct from the Bengal and Javan tigers. Stripes tend to dissolve into spots near their ends, it is darker in fur colour and has broader stripes than the Javan tiger.
Dark small spots between regular stripes. And on the back – the frequency of stripes is higher than in other subspecies. Flanks and hind legs are lines of small – males have a prominent ruff, which is especially marked in the Sumatran tiger.
Charles Frederick Partington wrote that Sumatran and Javan tigers were strong enough to break legs of horses or buffaloes with their paws, the Sumatran tiger is one of the smallest tiger subspecies and about the size of big leopards and jaguars. In agreement with this evolutionary history, even though they were not as heavy as Bengal tigers.
The Sumatran tiger is genetically isolated from all living mainland tigers, which form a distinct group closely related to each other. The Sumatran tiger population was estimated at 1, sumatran tigers persist in isolated populations across Sumatra.
