| Summary: | There are more than 10 million species on the planet, but why have some thrived where others have failed? The Wonder of Animals celebrates the most successful animal groups on Earth - from apes to elephants, ants to bears. Discover why, despite appearing clumsy and comical, penguins actually have an anatomy that is perfect for their environment and how the dominance of big cats is down to more than just their brawn. New science is combined with the very latest animal behaviour research and extensive BBC natural history HD archive footage to build a complete picture of each animal, revealing how its unique characteristics have contributed to its success. Chris Packham explores the anatomy and physiology of the largest land animal on the planet - the elephant. Their size seems ill-suited to surviving the most arid regions of Africa, but their inner workings allow them to defy the extreme heat of the desert and find food and water in seemingly barren landscapes, while their extraordinary memory enables them to repel predators. Chris reveals how hairs on the skin help keep elephants cool, how sensors in their feet may be able to guide them towards rain and how a unique pouch in their mouths stores water. Recent research has even discovered that elephants can distinguish between the voices of human friend and foe.
