A hedgehog, represented by the emoji 🦔, is a small mammal characterized by its spiky coat of sharp, needle-like quills. These adorable creatures have a rounded body, short legs, and a snout-like nose. Hedgehogs are known for their nocturnal nature and their ability to roll into a tight ball when they feel threatened, using their quills as a defense mechanism. With their endearing appearance and unique adaptations, hedgehogs have become popular pets and symbols of resilience and self-protection in the animal kingdom.
