A hedgehog is a small, spiny mammal known for its distinctive quills. These quills cover its back and sides, providing protection from predators. When threatened, a hedgehog can roll into a tight ball, presenting a formidable defense. They are primarily nocturnal, foraging for insects, worms, and other invertebrates at night. Hedgehogs are found in Europe, Asia, Africa, and New Zealand. They play an important role in controlling insect populations. Think of them as tiny, armored knights of the night!
