Inventions based on the examples that we find around us in nature are commonplace. Now a suit inspired by hedgehogs has been designed. The creator has drawn upon the hedgehog’s spines and ability to roll into a tight ball, both of which protect hedgehogs from predation. I'm not sure humans will ever take to wearing these suits on a daily basis as the wearer would be somewhat more cumbersome than hedgehogs, which can move very quickly when needed.
