The Sumatran tiger is found only on the Indonesian island of Sumatra in habitat that ranges from lowland forest to sub-mountain and mountain forest including some peat moss forests.
The Sumatran tiger is the smallest of the tiger subspecies as compared to the Siberian tiger which is the largest.
The smaller size of the Sumatran tiger makes it easier to move quickly through the jungle. Also, their stripes are narrower than other tiger species. The tiger's patterned coloring is an adaptation for camouflage in their natural habitat, which is often tall grass.
Webbing between their toes, when spread, enables the Sumatran tiger to be a very fast swimmer. It will, if given the chance, run hoofed prey, who are much slower swimmers, into the water.
