Yes, all hedgehogs have quills as a key feature of their anatomy. Quills are modified hairs that are stiff and sharp, providing hedgehogs with protection against predators. When a hedgehog feels threatened, it can roll into a tight ball, causing its quills to stand upright and create a formidable barrier. However, the level of quilling can vary among different species and individual hedgehogs. For example, African pygmy hedgehogs, commonly kept as pets, typically have softer quills compared to wild European hedgehogs. It's important to note that while quilling is a natural defense mechanism, young hedgehogs undergo a process called 'quilling' during which they lose their baby quills and grow adult ones, which can sometimes cause them to be more sensitive during this transition. Overall, quills are an essential part of a hedgehog's identity and survival in the wild.
