In the first of three programmes which travel progressively deeper underground to meet the bizarre creatures that inhabit the world beneath our feet and uncover the remarkable strategies by which they survive in a world devoid of light, biologist, Mike Dilger embarks on a most unusual soil safari.
Using sophisticated audio techniques, Mike heads underground on an earthworm, narrowly avoiding hungry moles and predatory fungi, as he uncovers a world of recycling and decomposition crucial to supporting life above ground!.
In the second of three programmes which travel progressively deeper underground to meet the bizarre creatures that inhabit the world beneath our feet, biologist, Mike Dilger abseils down a gaping hole, following the course of a waterfall into a deep underground cavern in the Yorkshire Dales.
Scrambling through the narrow, twisting passageways of the cave, Mike discovers how insects, bats, fish and birds are adapted to survive in this alien environment.
He also learns how a little love dust has revealed some amorous behaviour at the cave entrances!.
|01||03 LAST||The Rock Eaters||20031215|
In the final programme, its time to meet the rock eaters, extremophiles and the world of SLiMES as our amazing journey takes us deep into the earth's rocky crust; a world devoid of oxygen and light.
It is here that scientists have recently discovered unusual microbes that thrive at these depths, and which have forced us to re-draw the evolutionary tree of life and question where life itself really began; above ground, or, as appears more likely beneath our feet!.
