Hedgehog quills serve multiple purposes, primarily for protection and defense. These quills are modified hairs made of keratin, and when a hedgehog feels threatened, it can curl into a tight ball, causing the quills to stand erect and create a formidable barrier against predators. This adaptation helps deter potential threats, as the sharp quills can be uncomfortable or painful for animals that attempt to attack.

Additionally, quills can provide camouflage in their natural habitat, helping hedgehogs blend into their surroundings. In terms of social behavior, quills can also play a role in communication among hedgehogs, signaling their mood or readiness to defend themselves. Overall, quills are a vital aspect of a hedgehog's survival strategy.
