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.
When threatened, they roll in to a tight ball with just a mass of spines poking out. When relaxed, the spines lay almost flat. Hedgehogs are quite compact, reaching a size of around 5-8 inches in length. Estimates of expected life span vary widely, anywhere from 3-8 years, although 4-6 years is probably most typical. They are considered primarily insectivores as insects make up the largest part of their natural diet.
