The hedgehog's back contains two large muscles that control the position of the quills. The average hedgehog has about 5,000 to 6,500 quills that are strong on the outer surface but filled with air pockets on the inside. When the creature is rolled into a ball, the quills on the back protect the tucked head, feet, and belly, which are not quilled.
There are 16 species of hedgehog in five genera, found through parts of Europe, Asia, Africa and New Zealand. There are no hedgehogs native to Australia and no living species native to North America. Those in New Zealand are introduced.
