Sumatran tigers are endemic to the island of Sumatra, Indonesia and are the smallest and the rarest of all tiger subspecies. In the past, other subspecies of tigers roamed Indonesian forests, but both the Bali and the Javan tiger were brought to extinction in the 1940s and 1980s respectively. Adult male Sumatran tigers can reach 2,5m and 140kg and females 2m and 90kg. The Sumatran tiger is the apex predator of Sumatra, feeding mostly on wild pigs, muntjac and sambar deer as well as pig-tailed macaque. Sadly, fewer than 400 Sumatran tigers are estimated
to remain in the wild with their decline due to habitat loss and fragmentation and poaching.
