The Sumatran Tiger (Panthera tigris sumatrae) is found only on the Indonesian island of Sumatra. The wild population is estimated at between 400 and 500 animals, occurring predominantly in the island's national parks. Recent genetic testing has revealed the presence of unique genetic markers, indicating that it may develop into a separate species, if it is not made extinct. This has led to suggestions that the Sumatran Tiger should have greater priority for conservation than any other subspecies. Habitat destruction is the main threat to the existing tiger population (logging continues even in the supposedly protected national parks), but 66 tigers were recorded as being shot and killed between 1998 and 2000—nearly 20% of the total population.
Physical characteristics
The Sumatran Tiger is the smallest of all tiger subspecies, and the
Siberian Tiger is the largest. Male Sumatran Tigers average 8 feet in length from head to tail and weigh about 265 pounds. Females average 7 feet in length and weigh about 200 pounds. Its stripes are narrower than other subspecies of tigers' stripes, and it has a more bearded and maned appearance, especially the males. Its small size makes it easier to move through the
jungle. It has webbing between its toes that when spread, makes them very fast swimmers. It has been known to drive hoofed prey into the water, especially if the prey animal is a slow swimmer.
Habitat
The Sumatran Tiger is only found in Sumatra, an island in Indonesia. It lives anywhere from lowland forests to mountain forest and inhabit many unprotected areas. Only about 400 live in game reserves and national parks and the rest are spread out in areas that are quickly being lost to
agriculture. The reserves are not safe because despite conservation efforts, many tigers are killed by
poachers each year.
Diet
What a tiger eats depends on where it lives and how plentiful the prey is. They have very acute
senses of
hearing and
sight so the tigers are very efficient hunters. They are solitary animals and they hunt at night, stalking the prey slowly and patiently before attacking at the rear or sides. They eat whatever they can catch, commonly wild
boar and
deer, and sometimes
fowl, and
fish.
Orangutans could be prey, but since they spend a minimal amount of time on the ground, tigers rarely catch one.
Reproduction
Tigers can breed at any time of year, though they typically breed during the
winter or
spring, and the
gestation period is about 103 days. Normally they have 2 or 3 cubs, but can have as many as 6. The cubs are born with their eyes closed and weigh approximately 3 pounds each. Their eyes usually open by the tenth day, though some
zoo born cubs have been recorded to have their eyes open at birth. They only consume
milk for the first 8 weeks and after they can start trying harder food but still suckle for 5 or 6 months. The cubs first leave the den at 2 weeks old and learn to hunt at 6 months old. They can completely hunt for themselves at 18 months and at 2 years they are fully independent. They can live for about 15 years in the wild, and 20 in captivity.
