Why Hedgehogs Have Spikes (And Other Cute Defenses in Nature!)
Have you ever wondered why hedgehogs are covered in tiny spikes?
Are they dangerous? Do they throw their spikes?

Let’s discover the truth!
What Are Hedgehog Spikes?
Hedgehog spikes are not sharp weapons like porcupine quills. They are actually stiff hairs made of keratin — the same material as our fingernails!

When a hedgehog feels scared:
It rolls into a tight ball.
The spikes point outward.
Predators cannot easily bite or grab it.
Smart, right?
