After four weeks of extraordinary content, we are sadly drawing to a close of the #AfricaBBC series on BBC Knowledge. The last episode (airing this Sunday at 18h00 – DStv Channel 184) concludes BBC’s quest to show us the natural history of Africa and its wildlife like we have never seen it before.
Episode 5 – Sahara
The epic finale focuses on the last of the five geographic regions: the Sahara. In this episode we will uncover the barn swallow and how these birds make a truly remarkable journey flying thousands of miles across the expanding Sahara.

The crew also reveal how the species living in the Sahara have adapted to the high temperatures and harsh living environment, such as that of the silver ant in their ‘space suits’, the fringe toed lizard and the most awkwardly looking naked mole rats.
The silver ant is the Sahara's true desert survivor. When the Sahara formed most animals became fugitives. But this ant stayed, exploiting its 'space suit' of reflective silver hairs to reflect the heat and a pinpoint navigation system to ensure it always takes the shortest route back home, to shade and safety. © Felicity Egerton
A fringe toed lizard keeps a beady eye out for its prey, in a stake out under the scorching sun. The lizard is adapted to withstand the heat but sometimes even it has to flee for the shade before its prey emerges onto the sand?. © BBC 2012
A colony of naked mole rats take time off from their labours to rest in a communal chamber. Mole rats escaped the tyranny of the sun over north Africa by going underground, but in so doing became the most extreme of specialists; losing their hair, their sight and even the ability to control their own body temperature. Naked mole rats are some of the Earthâ??s strangest creatures - but that is what it takes to survive in north Africa. © Justin Maguire
If you caught last week’s episode – Africa on BBC Knowledge Episode 4: Cape – you’ll have seen the footage of a Great White shark feeding on a whale carcass off the coast of the Cape. To film that, cameraman Richard Matthews floated on a platform in the water next to the carcass so that he could get an eye-level shot of the shark feeding. Check it out:

The snow-capped Atlas Mountains seen from the edge of the Sahara desert. Within the last 10 000 years, a subtle change in the Earth'??s orbit precipitated dramatic change in north Africa â?? an apocalypse that turned the land into the desert it is today. But the very tops of the Atlas Mountains, seen on the horizon, were high enough to escape the disaster. © BBC 2012
Deep snow covers cedar trees, a rare image of north Africa. The Sahara has been a desert for less than 10 000 years. A shift in the climate caused a rapid and catastrophic transformation in the north of the continent. Savannah turned to dust, lakes dried out and forests fell â?? except this one, an island in the sky on the slopes of the Atlas Mountains. © Matthew Wright

The camel is the only pack animal able to withstand the rigours of the Sahara. But since a monumental shift in the Earth's climate caused the formation of the desert, and its expansion year on year, camels have had to walk further, much further, between sources of water. © Katrina Bartlam

A rare dung pile, left by travelling camels, might be the only chance a beetle has to provide food for their young. But the hot sand and burning sun turn the dung roll into a race against time, with the odds stacked against the beetle. © Katrina Bartlam
