The Sumatran tiger (Panthera tigris sumatrae) is a rare tiger subspecies that lived on the island of Sumatra. The tiger was named after the Indonesian island, Sumatra. The tiger is a critically endangered species as there are 441 to 679 adults living in the wild habitat. Many tigers are now living in the protected areas and national parks.
It is one of the smallest tigers averaging only 100 to 140 kg (220 to 310 lb) in the adult males whereas females weigh up to 75 to 110 kg (165 to 243 lb).
The size of an adult male is about 2.2 to 2.55 m (87 to 100 in) and female measures at 215 to 230 cm (85 to 91 in) in the overall body length.
Sumatran tigers make homes in coastal lowland forests and mountain forests at a height of 3,200 m (10,500 ft) above sea level. They like to make habitats which receive relatively less rainfall each year.
The Sumatran tiger eats banded pig, Indian muntjac, Malyan tapir, Sambar deer, great argus, Malyan porcupine, pig-tailed macaque, lesser mouse-deer, and greater mouse-deer.
The habitat loss and illegal trading forced the Sumatran tiger to live in isolated population. The largest population of tigers is in Kerinci Seblat National Park. However humans have cut down natural forests on a large scale just to fulfill their own needs.
