The desert hedgehog is just about the smallest hedgehog and can only grow up to just under 1 foot. The colour banding on their spines can make them look like a four-toed hedgehog, but these desert hedgehogs are usually identified by their dark muzzle. If they feel threatened, their muscles tense up and pull on the outer skin layer of the body, making its spines stick out in every which way. In addition, these spines tend to be longer than the spines of other hedgehogs, meaning better protection from the predator. This also makes it so that people can barely catch one.
