David Attenborough has spent a lifetime documenting the natural world. He's met a great number of nature's most extraordinary creatures yet there are certain stories of bewildering animals that continue to intrigue him - from the peculiar patterns of a zebra's stripes to the evolutionary quirk of the egg-laying platypus. Each episode of this captivating five-part series explores the stories behind two natural curiosities, linked together by a common theme. Filmed on location in the UK, David's gift for storytelling combined with wonderful images of the animal subjects creates a documentary series unlike any other he has made before.
