With a single horn of up to 10 inches, this smaller subspecies of rhinoceros is differs from its more commonly recognized cousins due to its smaller head and fewer skin folds.
The last Javan rhino in Vietnam was poached in 2010.
Today, the only remaining population of this species resides in Ujung Kulon National Park in Java, Indonesia. In addition to risks of poaching, inbreeding, disease, and the invasive plant species that are overtaking the Javan rhinos' food supply, this National Park lies in the shadow of the Anak Krakatau volcano and is highly vulnerable to tsunamis. One natural disaster in the region could completely wipe out what remains of the Javan rhino.
The World Wildlife Fund is aiding in the species rehabilitation at the Ujung Kulon National Park in hopes of cultivating a habitat that will support a much larger population of the species.
