Here's why this is significant:
* Unlike domestic horses, which have long, flowing tails, the Przewalski's horse has a tail that is much shorter and stands out from the body.
* The tail is covered in short, stiff hairs which give it a bristly appearance.
* This type of tail is thought to help the horse keep cool in hot weather by allowing air to circulate around the hindquarters.
So, when picturing a Mongolian wild horse, remember that it has a distinctive, stubby, and upright tail!
