Saiga antelope are large migratory herbivores that live in the dry steppe grasslands and semi-arid deserts of Central Asia. The saiga is among one of the world’s most ancient living animals. They were once very abundant, roaming alongside mammoths and saber-toothed tigers over vast landscapes spanning from the British Isles to Alaska. Saiga antelope are a nomadic species and live in large herds numbering, at times, in the thousands (especially during periods of migration). The saiga’s coat changes depending on the season. In the summertime, their coat is short and ranges from a sandy yellow to almost red in color. In the winter months, the Saiga’s coat becomes both paler and thicker. The Saiga’s large, shotgun shaped nose may look unusual, but it is perfectly suited for their environment. The Saiga’s extra-long snout is thought to, in the summer, keep debris from entering the lungs during dust storms and, in the winter, warm air before it reaches the lungs. The females' ability to twin consistently is unusual among hoofed mammals (ungulates) and lends to the saiga’s resilience as a species as they face several hardships that contribute to the catastrophic fall in numbers.
