Pinning the ants to the hot sand surface, the spiders first cook them to death before dragging them under.
In the Namib, even the toughest animals struggle with the heat. Gemsbok trek1 to the crests2 of the highest dunes3 to seek relief in the breeze.
With no cloud cover, solar radiation blasting the desert is intense. The mid-day sand is so hot. It's like a bed of burning coals. The Namib quickstep. Over millions of years, you learn to keep your claws cool. Pushed by the wind, the dunes avalanche4. The Namib's residents can't fight the tide.
Though the dunes are unstable5, they provide a home for a remarkable6 creature. The trapdoor spider only builds its nest on the top of the steepest dunes. It's learned to do this because it has a very aggressive enemy, a wasp7, which relentlessly8 scours9 the sand.
Though its eyesight is poor, the wasp has very sensitive hairs on its legs which can pick up the slightest scent10 of a spider. When it finds a nest, the wasp quickly works out how deep the burrow11 is. If it's shallow, the wasp starts digging for up to two hours. It's hard work against the slipping sand.
