The Sumatran tiger ("Panthera tigris sumatrae") is a subspecies of tiger found 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, which isolate Sumatran tigers from all mainland subspecies.cite journal | author = Cracraft J., Feinstein J., Vaughn J., Helm-Bychowski K. | year = 1998 | title = Sorting out tigers ("Panthera tigris") Mitochondrial sequences, nuclear inserts, systematics, and conservation genetics | journal = Animal Conservation | volume = 1 | pages = 139–150 | doi = 10.1111/j.1469-1795.1998.tb00021.x]

Characteristics

The Sumatran tiger is the smallest of all still existing tiger subspecies. Male Sumatran tigers average 234 cm (7 feet, 8 inches) in length from head to tail and weigh about 136 kg (300 pounds). Females average 198 cm (6 feet, 6 inches) in length and weigh about 91 kg (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 dense rain forests. It has webbing between its toes that, when spread, makes Sumatran tigers very fast swimmers. It has been known to drive hoofed prey into the water, especially if the prey animal is a slow swimmer.

Sumatran Tigers commonly prey on larger ungulates, like wild boar, tapir and deer, and sometimes also smaller animals, like fowl, and fish. Orangutans could be prey, but since they spend a minimal amount of time on the ground, tigers rarely catch one.

Genetics and Evolution

Analysis of DNA is consistent with the hypothesis that the Sumatran tigers have been isolated after a rise in sea level at the Pleistocene to Holocene boarder about 12.000-6.000 years ago from other tiger populations. In agreement with this evolutionary history, the Sumatran tiger is genetically isolated from all living mainland tigers, which form a distinct group, closely related among each other.

Conservation

In 2007, the Indonesian Forestry Ministry and Safari Park established cooperation with the Australia Zoo for the conservation of Sumatran tigers and other endangered species. The cooperation agreement was marked by the signing of a Letter of Intent on 'Sumatran Tiger and other Endangered Species Conservation Program and the Establishment of a Sister Zoo Relationship between Taman Safari and Australia Zoo' at the Indonesian Forestry Ministry office on July 31, 2007. The program includes conserving Sumatran tigers and other endangered species in the wild, efforts to reduce conflicts between tigers and humans, and rehabilitating Sumatran tigers and reintroducing them to their natural habitat.
