SUMATRAN TIGER

The Sumatran tiger (Panthera tigris sumatrae) is a critically endangered subspecies of tiger native to the Indonesian island of Sumatra. It is the smallest of all tiger subspecies, with males typically weighing between 100-140 kg (220-310 lbs) and females weighing between 75-110 kg (165-243 lbs). This smaller size is an adaptation to the dense forests and rugged terrain of their equatorial island habitats.

Save the Sumatran tiger

According to the Indonesian government, approximately 600 Sumatran tigers remain in the wild as of 2024. How much over or under that estimate is a matter of conjecture since tiger population surveys have been restricted to a few National Parks, which do not cover all of the species’ range.
