There are 17 different kinds of hedgehogs around the world. Hedgehogs are small, spiny mammals. They can have as many as 6,000 quills. When in danger, they roll into a tight ball to protect themselves. They are nocturnal animals, so they usually sleep during the day. They like to eat beetles and caterpillars. The average lifespan of hedgehogs is 4 to 7 years in the wild.
