![]() They had long, thin stripes and a narrow face with a relatively long and narrow nose. They were larger than the closely related Bali tigers of neighboring Bali Island, and weighed up to 310 pounds. Distinctive Javan Tiger FeaturesĬompared to the other modern tiger subspecies, Javan tigers were smaller on average, which was an adaptation to the size of their main prey the Rusa Deer. Most likely the fleeting glimpses of big cats are the Sunda clouded leopard in Borneo or the critically endangered Javan leopard. There are still occasional rumors of sightings in the remote hilly jungles of Borneo and Java, but no firm evidence to confirm that they exist, despite several surveys and camera trap studies. It is not known, if they existed, why tigers went extinct in Borneo. Skins, skulls, teeth, and wall paintings of tigers have all been found in Borneo. Tiger teeth were used by the leaders of tribal communities in Borneo for lie detecting and were considered to be powerful. This scientific name previously referred to the Javan tiger as a subspecies and is now used to classify all three Indonesian island tigers.įossilized tiger bones and teeth have been found on Borneo Island and in Palawan in the Philippines suggesting that descendants of the Sunda tigers also existed in these places around 12,000 years ago. Recently, global tiger experts updated tiger taxonomy, grouping all three as one tiger sub-species called the Sunda Tigers (scientific name Panthera tigris sondaica). While evolving from a common ancestor, recent mtDNA analysis confirmed that the Bali, Java and Sumatran tigers are indeed unique tiger subspecies. It is thought that each tiger subspecies became isolated and adapted uniquely to its island home when rising sea levels after the last Ice Age (about 10,000 years ago) isolated the tigers into island populations and restricting gene flow. The extinct Javan and Bali tigers, together with the critically endangered Sumatran tiger, all evolved from a single tiger ancestor called the Sunda tiger. Indonesia is unique among tiger range countries as the only place in the world where tigers evolved on islands. Today only the Sumatran tiger remains, hanging on by a thread and critically endangered. It was one of the three Indonesian tiger subspecies: the Javan tiger, the Bali tiger, and the Sumatran tiger. The Javan Tiger is a now extinct subspecies of tiger that adapted and evolved to live on the island of Java in Indonesia.
