How do hedgehogs protect themselves from predators?

Hedgehogs protect themselves by rolling into a tight ball, exposing only their sharp spines. Their spines act as a defence mechanism, deterring predators from attacking. When threatened, hedgehogs use strong muscles to pull their head, legs, and belly inward, creating a nearly impenetrable shield. They also produce hissing or clicking sounds to warn potential threats. This effective defence strategy has allowed hedgehogs to survive in diverse environments despite their small size.
