Pseudoryx

Pseudoryx is a genus of bovid mammals that contains a single living species, the saola (Pseudoryx ngathinae). This elusive animal is often referred to as the "Asian unicorn" due to its rarity and the difficulty in observing it. The saola is native to the Annamite Mountains of Vietnam and Laos. It is characterized by its long, slender, and nearly parallel horns, which are present in both males and females. Its coat is typically dark brown with white markings on the face and throat.

The saola is a herbivore, feeding primarily on leaves and young shoots. It is a solitary animal, and very little is known about its social behavior or breeding habits. It was first scientifically described in 1992, making it one of the most significant mammalian discoveries of the 20th century. Despite its recent discovery, the saola is critically endangered. Its population is estimated to be very small, likely only a few hundred individuals. The primary threats to its survival include habitat loss due to agricultural expansion and logging, as well as hunting, often through snares set for other animals. Conservation efforts are underway to protect the saola and its habitat, but its secretive nature makes these efforts challenging.
