The Javan rhino is one of the three rhino species found in Asia. They are the most endangered of all the five species of rhino with only as few 50 thought to still survive in the wild today. Extinction for the Javan rhino is a very real possibility.

Protection of the last remaining population at Ujung Kulon National Park in Indonesia is having a good degree of success with no poaching incidents reported since 2005. It is believed only the male of the species has a single horn with the females not carrying any horn.

The Javan rhino spends large periods of the day wallowing in water holes and mud baths. Their long upper lip is very distinctive and allows the Javan rhino to browse on trees, twigs and leaves, although they do also graze on open grassland too.
