Yaks are not native to the Gobi Desert, but rather were introduced by the nomadic people of Tibet. These large creatures cause no harm to the ecosystem of the desert, and improve the quality of life for the very few people that live in the desert's harsh conditions.
Przewalski's horse, the last of the world's wild horses, is critically endangered because of hunting and the harsh lifestyle of the desert. They are only about four feet high at the shoulder. In the wild, it lived in groups, which included a dominant stallion and several mares. Until recently, the horse live in the Gobi Desert, but it now lives only in captivity. (A reintroduction program has been initiated)
The Bactrian Camel is an iconic desert-survival machine. Known for it's two humps, this camel stores water for great lenghts of time to live in the arid conditions. It has large hooves to support its weight on the shifting dunes of the Gobi.
The Gobi Snow Leopard lives in the more mountainous region of the Gobi, and lives comfortably in the frigid weather with its thick fur coats. Although it can struggle to find food in the desert waste land, when it does the snow leopard is well equipped to take down prey with its muscular legs and sharp claws.
The central Asian Viper, known for it's aggressiveness, has a deadly bite that will kill a man in hours. It employs the technique of a wave-like motion to move faster over the Gobi's dunes than any other creature there. It can survive for months without food, making this snake perfect for this harsh environment.
The saxual tree is well equipped to survive in the Gobi desert because its thin leaves retain the little water it receives very well. Also, it has very tough roots and stems to resist the strong winds found in this region
The wild onion plays a very niche role in the desert, as it is one of the few food sources that can even survive in the harsh conditions. It survives mostly under ground to stay out of the overbearing sunlight.
The Stalwart is a surviving power house. This plant can live in any region of the world that has some sort of ground for it to reside in, and is a well known pest in the US. It would make sense then that this ugly weed originated in the harsh climate of the Gobi desert.
