David Attenborough explores two deserts in Africa's south west, where he sees meerkats, black rhinos, giant insects and a giraffe fighting to defend his resources.
In Africa's south west corner, two extraordinary deserts sit side by side. In the Kalahari scrublands, meerkats are outsmarted by a wily bird, solitary and belligerent black rhinos get together to party, and giant insects stalk huge flocks of birds.
Rain almost never falls in the Namib - instead it must make do with vaporous, vanishing fog. The creatures here have gone to the extremes, as spiders wheel to escape and a desert giraffe fights to defend his scant resources.
