What unique adaptation does an African hedgehog have that allows it to protect itself predators?

African hedgehogs have a unique adaptation in the form of their spiny quills, which cover their backs. When threatened, they can curl into a tight ball, with the spines facing outward, making it difficult for predators to attack. This defensive behavior, combined with their ability to quickly hide in burrows or underbrush, helps them effectively evade potential dangers in their environment.
