Animal bodies - what do they feel like?
Different animals have different types of skin - some are rough, and some are smooth; some are slimy and some are spiky. Porcupines and hedgehogs have spikes for protection; snakes can have rough scales to make noises; slugs and snails are slimy to help them move; and tortoises have hard shells for protection. First broadcast as part of the CBeebies series Our Planet.
