About the Documentary:
"Just over 400 million years ago creatures left the seas to move onto land. They were the invertebrates. Since then
they have become the most successful group of animals, adapting to every environment on earth. Now, for every human
there are 200 million of them. Their largely unseen world is now revealed as David Attenborough tells the story of the
land-living invertebrates."

"David Attenborough tells the story of the land-living invertebrates. He delves into the private life of Europe's
dramatic leopard slug, a common garden resident with a truly bizarre end to its marathon mating ritual; watches the
courtship ballet of tiny springtails on the underside of a leaf; sees swarms of bright red South African millipedes
find partners, and in the caves of Venezuela meets the giant bat-eating centipede."
