- Saola, known as “The Asian Unicorn” is one of the endangered species in Vietnam, has been recognized on Việt Nam’s Red List. Saola is an animal from ancient times and apparently the rarest large mammal in the world. Saola are recognized by two parallel horns with sharp ends, which can reach 20 inches in length and are found on both males and females. They are found only in the Annamite Mountains of Vietnam and Laos. Nowadays, there are Saola Nature Reserves in Quang Nam and Hue established to protect the creature and its habitat. The biggest problem is habitat loss. In order to protect Saola, we should raise fund and conserve its natural habitats.
