Africa - Sahara, tonight, 9pm on BBC One
This week David Attenborough takes us to Northern Africa and, arguably, the greatest desert on Earth, the Sahara. On the fringes, huge zebras battle over dwindling resources and naked mole rats avoid the heat by living a bizarre underground existence (see clip below). Within the desert, tiny swallows navigate across thousands of square miles to find a solitary oasis, camels seek out water with the help of their herders, while dung beetles gather their poo and roll them across mountainous sand dunes.. some of which 'sing'! Sounds like fun, but the reality is that in the desert life can be tough. When nature is overrun, some are forced to flee, some endure, and a few seize the opportunity to establish a new order.
This Dung Beetle makes a mountain out of a sand dune.
The Naked Mole Rat
David Attenborough has chosen the naked Mole Rat as one of his Natural Curiosities in his new series on the Eden Channel. This clip shows how natural behaviour of the mysterious Mole Rat was filmed for this weeks episode of Africa.
