The Wonder of Animals: Elephants

PëRMBLEDHJE

Chris Packham explores the anatomy and physiology of the largest land animal on the planet, the elephant. Its size seems ill-suited to surviving the most arid regions of Africa, but its inner workings allow it to defy the extreme heat of the desert, and find food and water in seemingly barren landscapes, while its extraordinary memory enables it to repel predators. Here, Chris reveals how hairs on the skin help to keep the elephant cool, and how sensors in its feet may be able to guide it toward rain.
