At a mind-numbing 8,848 metres high Everest is one of the most hostile places for life on Earth.
在令人目眩的海拔8848米的高度看，珠穆朗瑪峰是地球上最危險(xiǎn)的地方之一。
Hundreds of people have died trying to conquer it. But when climbers first reached the ice fields three quarters of the way up the mountain,something had already beaten them to it.

This jumping spider is the highest permanent resident on the planet. Totally at home amongst the glaciers of Everest, it scours the slopes for wind-borne prey such as springtails.

The ideal way to get around in rocky terrain. But like all mountaineers,they always secure a safety line first.A springtail grazes on detritus, unaware that it's being stalked by such an acrobatic predator.
這是在山地中行走的理想方法。但像其他的登山者一樣 他們也總是先確認(rèn)哪里是“安全線”。一個(gè)彈尾蟲(chóng)正盯著碎石屑，對(duì)這個(gè)耍雜技般的掠奪者的潛行跟蹤渾然不覺(jué)。
