Quote:One of the nation's most popular presenters, Sir David examines 40 marvels of the natural world from his extraordinary and pioneering experiences.

What was Sir David's first pet? Which animal would he most like to be? How did he track down a giant earthworm? Why does he respect rats? And what did he do when confronted by a 10-foot-long reptile?

His enthusiasm is as infectious as ever and conveys a unique fascination on topics as diverse as the sloth, monstrous flowers, the platypus, dragons, the fire salamander, the coelacanth, the dodo, bird's-nest soup and the large blue butterfly. So listen to these stories to find out the real reason why animals sing, the story behind a 150-million-year-old feather and what it is about snakes that really unnerves Sir David.
