The team head deep into the Australian outback to explore the ultimate desert survivor.
We don't think of Australia as the home of camels, but in the middle of this vast island there are over a million feral dromedaries roaming. European settlers introduced them over a century ago to help build Australia's railways and explore the outback.
But with the advent of roads, cars and trucks, camels were no longer needed, so their owners released them into the desert.
Mark Evans and Joy Reidenberg brave the baking desert to dissect a camel. They uncover the secret of the camel's hump and investigate how its elastic legs, stretchy lips and pedestal (a strange bump on its chest) are among the many surprising adaptations that enable the camel to thrive in such a dry and hostile environment.
Meanwhile, champion camel-jockey Glenda Sutton shows Simon Watt how to break in and ride a wild camel. Simon discovers that, although this animal does spit and kick, there's much more to marvel at than its cantankerous reputation.
