What rhinos occur in the South-east Asian region?
There are two species : Javan rhinoceros (scientific name Rhinoceros sondaicus) with one horn, which occurred in Borneo in prehistoric times and survived in Sumatra until the nineteenth century and in Peninsular Malaysia until the twentieth century. Now, the species occurs only in Ujung Kulon National Park on Java island (Indonesia), and Cat Tien National Park in Vietnam. The other species is known either as the Asian Two-horned rhinoceros or, more commonly, as the Sumatran rhinoceros (Dicerorhinus sumatrensis), although the latter name is misleading because the species once occurred throughout much of Southeast Asia. Now, this species occurs only on Sumatra and Borneo islands, with a few, possibly non-viable individuals in Peninsular Malaysia.
