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.
Porcupines can repel foes because their quills will stick in the skin. Yes, hedgehogs have quills like porcupines, but they are not barbed nor are they able to âshootâ from the hedgehogâs body like a porcupineâs. A hedgehogâs back is covered in approximately 7,000 modified hairs called quills.
