Why do hege hogs have spikes?

Answer 1

Hedgehogs have spikes, or quills, as a defense mechanism against predators. These sharp, stiff hairs can deter potential threats by making the hedgehog less palatable and more difficult for predators to handle. When threatened, hedgehogs can curl into a tight ball, which further protects their vulnerable body by presenting only their spines. This adaptation has evolved over time to enhance their survival in the wild.
