The snow leopard is the world's highest-living big cat.
But there's another,smaller predator that ranges even higher, almost to the roof of the world.

At a mind-numbing 8,848 metres high, Everest is one of the most hostile places for life on Earth.
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.

Chinese call this fierce little hunter the "fly tiger".

Jumping spiders are found all over the world.

Their eight eyes include an oversized central pair, which act like powerful binoculars to spot potential victims.

They use hydraulic pressure to work their legs like pistons, catapulting up to 30 times their own body length.

The ideal way to get around in rocky terrain.

But like all mountaineers,they always secure a safety line first.
