Did you know hedgehogs are nature's little armored adventurers? These spiny mammals belong to the subfamily Erinaceinae and have been around since the Late Eocene – that's over 15 million years of survival! Hedgehogs are nocturnal creatures, relying on their keen sense of smell and characteristic spines – stiff hairs made of keratin – for protection. When threatened, they roll into a tight ball, turning into a spiky fortress!

With 17 species spread across Europe, Asia, and Africa (and introduced to New Zealand), these omnivores enjoy a diet of insects, snails, berries, and even the occasional frog or snake. Some hedgehogs even have partial immunity to snake venom – how cool is that?

But there's more: hedgehogs "anoint" themselves with frothy saliva when encountering new scents, possibly to camouflage or confuse predators. From their quirky habits to their adorable "snuffles," hedgehogs are truly fascinating creatures! 🦔
