In 1954, a young television presenter was offered the opportunity of a lifetime - to travel the world finding rare and elusive animals for London Zoo's collection, and to film the expeditions for the BBC.

This is the story of those voyages. Staying with local tribes while trekking in search of giant anteaters in Guyana, Komodo dragons in Indonesia and armadillos in Paraguay, he and the rest of the team battled with cannibal fish, aggressive tree porcupines and escape-artist wild pigs, as well as treacherous terrain and unpredictable weather, to record the incredible beauty and biodiversity of these regions. The methods may be outdated now, but the fascination and respect for the wildlife, the people and the environment - and the importance of protecting these wild places - is not.

Written with his trademark wit and charm, ADVENTURES OF A YOUNG NATURALIST is not just the story of a remarkable adventure, but of the man who made us fall in love with the natural world, and who is still doing so today.
