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.
* Hedgehog's do NOT have quills, they have spines. * They are a small animal only growing to an average 6 and have spines that are 1/2 - 1 long. * A hedgehog's spine is a hollow hair hardened with keratin. * A hedgehog has 5000 - 6500 spines. * They are capable of running in short bursts up to 6 feet per second.
