In Everest Mountain only few animals can live at the highest altitude of Tibet and Nepal. The highest altitude where some extreme animal can live is 6,100m. And those animals are blue-sheep, Tibetan gazelle, Pika, yak and certain birds.


In low altitude there are some excellent animal who can survive from 5,000m to 5,750m. Those animals are Himalayan Thars, snow leopard, Himalayan goral, musk deer, The Himalayan yak, red panda, and the Himalayan black bears.


There are also certain birds live in Mount Everest area. On the ground you will see Tibetan Snowcocks but they are very rare. You will also be able to see Himalayan Blood Pheasant and the Danfe Pheasant if you are lucky enough. In the sky you will be able to see Alpine Choughs or Yellow Bill Choughs which can built nest in high altitude above 6,000m. The Bar-Headed Geese can be seen during migration and probably they are the highest flying bird in the world who can fly above the peak of mount Everest. The most available birds are magnificent Bearded Eagle and the Himalayan Griffons. 

I don't think so that the conditions on the top of the Everest are feasible for any animal to live.

Secondly there is no food so that animals can survive.

Oxygen pressure there is also on lower side so its hard to survive for any living being to live there.  

Wherever the place is and however the weather there must be animals that live and are able to live there, Even though you are above altitude, you do not escape the observation of these poisonous animals, which are at low enough air pressure to breathe even harder. You still can't hide from the attacks of this living thing. Euophrys omnisuperstes, or better known as Himalayan spiders, can jump and hide in the slopes of a mountain slope.

The hideout was done to outwit the climbers on the mountain. Because of this, this creature was designated as a mountain eternal resident whose peak was in the Tibet region. The climbers claimed to have seen this creature when it was above an altitude of 6,700 meters or approximately 22 thousand feet. This spider is a species belonging to the Salticidae family. This species is also part of the genus Euophrys and the order Araneae.

Spiders that are commonly found in the Nepalese region eat any insects around them. They are almost the only animals that are permanently based at heights like birds. However, this spider belongs to the category of deadly animals in the world.

The altitude and temperature at the top of mt. everest is inhabitable for regular living animals especially hotblooded animals.
