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.
Hedgehogs are native to mainland Britain and are also found throughout northern and western Europe. Related and similar species are also found as far as north Africa, the Middle East and central Asia. There are 16 species of hedgehog in five genera, found through parts of Europe, Asia, Africa and New Zealand. 1  There are no hedgehogs native to Australia and no living species native to North America. 2  The pre-breeding season population estimate of Hedgehogs in Britain is around 1,555,000.
