It's hard to imagine something or someone living at 6700 meters of altitude, but it costs more if what survives at that altitude where there is hardly any oxygen and the temperatures go down to the marrow, is a spider.
Discovered in 1924 on Mount Everest, the Himalayan jumping spider (Euophrys omnisuperstes) or "the one above all" haita under icy ground stones. This makes it probably the predator that lives permanently at higher altitude on Earth.
The Himalayan jumping spider was first described in 1975, and it is believed that it feeds on insects that reach such exaggerated altitudes due to wind currents.
That implies an extraordinary ability to resist both low temperatures and low atmospheric pressure. Further, can last a long time without eating food.
Jumping spiders are known for their curiosity. If a human hand approaches, instead of fleeing to a safe place like most spiders, they jump and turn to face the hand. They also have specialized structures to adhere to the smooth surfaces, called scoopulas, which consist of a cushion of hairs, each finished in a suction cup, which are used to scale virtually any terrain.
