The Sumatran tiger is found exclusively on the Indonesian island of Sumatra. Their habitat ranges from lowland forest to mountain forest and includes evergreen, swamp and tropical rainforests.
Like all tiger subspecies, fathers do not participate in raising cubs. They can communicate with one another by rubbing heads, roaring and grunting. Scent marks and visual signposts, such as scratch marks, allow tigers to track other tigers in the area and identify individuals and territories. Although tigers prefer to be solitary, they interact regularly when crossing overlapping territories.
Their live in the wild for 10 to 15 years and can reach 20 years in captivity.
Sumatran tigers are carnivorous. Their diet mostly consists of ungulates, birds, fish and monkeys, all of which are found in the islands of Indonesia. The Sumatran tiger does not climb very well, so prey that can get high up into the boughs of the surrounding trees often evade capture. The Sumatran tiger is a good swimmer, however, and can pursue its prey in water quite efficiently.
Between 500 and 600 Sumatran tigers are estimated to remain in the wild. They are considered a Critically Endangered animal.
Sumatran tigers are the smallest tiger. They are such proficient swimmers that they can easily cross rivers and lakes up to five miles wide.
Why are they Endangered?
The Sumatran tiger’s population is dwindling rapidly due to illegal hunting. China is considered the largest consumer and producer of manufactured products containing tiger parts and poachers kill these tigers to satisfy that need. Deforestation is also a problem for the Sumatran tigers. As forests are being destroyed, the natural habitat of the tiger and its prey disappears, causing them to die out steadily.
