With just 58-68 of these rhinos that live in Ujung Kulon National Park in Java, Indonesia, these are the most threatened of all rhinos. Most were killed by trophy hunters during colonial times. Vietnam’s last Javan rhino was poached in 2010. They are killed for their horn, which is coveted in parts of Asia for its supposed medicinal qualities and as an ornament. Even in the park, poaching remains a threat.
