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.
The average hedgehog has 5,000 -7,000 quills. Quills are hard on the outside, filled with soft air pockets on the inside. There are 2 large muscles on either side of a hedgehog's back to raise and lower its quills and curl into a ball. This is a hedgehog's only defense.
