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.
Hedgehogs have changed little over the last 15 million years. Like many of the first mammals they have adapted to a nocturnal way of life. The male Hedgehog is called a âBoarâ and is slightly larger than a female Hedgehog which is called a âSowâ.
