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.
Of the many species of tenrecs, there are two that superficially resemble hedgehogs: the Greater Hedgehog Tenrec and the Lesser Hedgehog Tenrec. The inclusion of hedgehog in their names can be misleading - it is because of that resemblance, not because they are related to hedgehogs. The closest relatives to tenrecs, through a common ancestor, are actually elephants, sea cows, hyraxes, and aardvarks. While there are a handful of tenrec species commonly kept as pets in the UK and Europe, the only species that is currently available in the US is the Lesser Hedgehog Tenrec.
