Fairytale beast
Saola, also called "Asian unicorns," were first discovered in 1992. The find was astounding. A large mammal hadn't been discovered since the 1930s.
Rare and delicate
Although they have two horns, the animals got their nickname because of their secretive ways. They're so mysterious that researchers began to compare them to unicorns.
This female was captured in 1996. The animals don't do well in captivity, and typically die in just days or weeks after capture.
Telltale bones
Two decades ago, Vietnamese scientists identified the new species only from strange, horned skulls villagers had collected in the lush forests of the Annamite Mountains along the Vietnam-Laos border.
Fleeting glimpse
Scientists have never observed saola in their natural environment, and the secretive creatures have been caught on film in the wild only once, by a camera trap, in 1999. This is one of those images.
Dangerous ground
