Mammals are divided into three subclasses (eutheria, matatheria, and prototheria ) and 26 orders.
Antelope belongs to the subclass eutheria.
Some antelope species have been added to the endangered list. One of the most well known antelopes is the Tibetan antelope. Their fur, which is the shahtoosh, is used to make luxury clothing. Some illegal hunters killed the Tibetan antelope and do illegal trade to gain money. This is one of the reasons that push the Tibetan antelope to the brink of extinction.
