Animals In The Wild Vol. 1: Fangs And Claws

Humans invented axes and knives because their own teeth and nails were too weak to tear through the hides of animals. Lion and hyenas have powerful claws and teeth to rip flesh and crush the bones of their prey. This program looks at ways different animals have developed their own tools to eat, fight and defend themselves. Rows of razor sharp shark teeth, the fine straining filters of flamingos, and straw-like proboscis of aphids all have parallels in the way we process our food. Animated graphics illustrate the similarities and show how nature's utensils work.
