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 15 species of hedgehogs, most of which are found in the wild in Africa, Asia and Europe. These little, rodent-like critters are covered in spines, which provide them a great deal of protection. Their eyesight is poor, but their keen hearing and sharp sense of smell help them get by quite well in the world.
