What Are They Like?

The Sumatran tiger is the smallest of the tiger subspecies. Adult males can grow up to 8 feet (2.4 meters) long, measured head to tail, and can weigh up to 300 pounds (136 kilograms). The mane of the Sumatran tiger is considerably thicker and more pronounced than that of other tigers. Its stripes tend to be narrow and dark. Sumatran tigers have webbing in between their toes, which allows them to easily catch prey in the water.

Where Do They Live?

Sumatran tigers are found only on the Indonesian Island of Sumatra, and are the last remaining Indonesian tigers. They inhabit the island's lowland and montane forests, as well as the Sundaland rivers and swamps.

Did You Know?
The roar of a tiger can often be heard from more than a mile away.

How Are Babies Made?

A mother tiger typically gives birth to two to three cubs at a time. The gestation period for a Sumatran tiger is about a hundred days. Cubs are born blind and helpless, and are wholly dependent on their mother for the first few months.

What Do They Eat?

The Sumatran tiger's diet consists mainly of wild boar and deer, and when those are scarce they will eat whatever prey is available.

Did You Know?
A group of tigers is referred to as a "streak."

What Do They Do?

The Sumatran tiger's small size allows it to swiftly move though dense forest terrain. Sumatran tigers hunt by stalking their prey, and tend to live alone.

How Concerned Should We Be?

The International Union for the Conservation of Nature (IUCN), which keeps a "Red List" of species in danger worldwide, lists the Sumatran tiger as "critically endangered." The biggest threat to Sumatran tigers is the encroachment of humans into its territories. Rapid deforestation and poaching are the main factors behind their population decline. Less than 400 individuals are estimated to exist in the wild. Even though the hunting of Sumatran tigers has been outlawed, poachers continue to illegally capture and kill them.

What's Being Done?

The World Wildlife Fund (WWF) has taken successful measures to protect the Sumatran tiger's natural habitat by securing a vital area, Tessa Nilo, as a national park.
