The hedgehog makes its home in gardens, hedges and woodland across the UK, Ireland and Europe. This mammal is about 25 centimeters long. Living there is not easy, but the hedgehog's body and habits are a good match for it.
One reason the hedgehog survives is about 5,000 to 7,000 sharp spines, which protect it when it rolls into a tight ball. (Spines means stiff, sharp hairs.) It also has a strong sense of smell, which helps it find insects in the dark.
The hedgehog is a carnivore, which means it is an animal that eats other animals. Its food includes beetles, caterpillars and earthworms. To find food, it hibernates through the winter in a nest of leaves.
Young hedgehogs are called hoglets. Hoglets are born with soft spines that harden within a few days. A hedgehog can travel more than a kilometer in one night looking for food.
