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.
According to Wikipedia: Hedgehogs have a relatively long lifespan for their size. Larger species of hedgehogs live 4â7 years in the wild (some have been recorded up to 16 years), and smaller species live 2â4 years (4â7 in captivity), compared to a mouse at 2 years and a large rat at 3â5 years.
