Sumatran Tiger: Lifecycle, Threats, Diet and Hunting Habits


The Sumatran tiger, a tiger subspecies indigenous to Indonesia’s Sumatra island, is the smallest among its kind. Its evolution on an isolated island likely led to its smaller size.

With closely packed stripes and darker orange fur, the Sumatran tiger is well-adapted to its tropical rainforest environment. Its unique features include a distinctive beard and mane.

The Sumatran Tiger: Lifecycle, Threats, Diet and Hunting Habits

Diet and Hunting Habits:

Sumatran tigers are carnivorous, feeding on a variety of animals including fish, monkeys, wild boar, tapirs, and deer.

They are nocturnal hunters, preferring to ambush their prey, a tactic necessitated by their ability to only run at high speeds in short bursts.

Increasing habitat loss forces these tigers to travel greater distances, sometimes up to 18 miles, to find food.


These tigers lead solitary lives except during mating. A female Sumatran tiger’s gestation period lasts around 100 days, resulting in a litter of one to six cubs.

The cubs remain with their mother for approximately two years.


The Sumatran tiger is critically endangered, primarily due to habitat loss and poaching. The expansion of oil palm plantations significantly contributes to the loss of their habitat.

Additionally, poaching persists even in protected areas. Tiger parts are in demand for various products, including tiger bone wine, jewelry, and as status symbols in some Asian cultures.

Conservation Efforts:

Many Sumatran tigers reside in protected areas like national parks, where anti-poaching patrols offer some defense. Indonesia, the largest Muslim country in the world, has also issued a religious decree against poaching.

Conservation strategies include managing tiger habitats sustainably, enhancing protections, and community development programs to deter poaching.

Captive breeding programs outside Indonesia aim to bolster understanding of tiger behavior and reproduction to aid conservation.

The Larger Crisis:

Tiger populations globally are facing a sharp decline, with less than 4,000 in the wild.

The Sumatran tiger, with fewer than 600 remaining in the wild, is critically endangered, largely due to deforestation for palm oil production, leading to significant habitat loss.

This ongoing deforestation in Sumatra puts the future of these tigers in peril.
