Strange Name Hedgehogs are small woodland animals, although they are known to live in deserts as well. The name ‘hedgehog’ comes from their appearance around garden hedges and the cute pig-like grunt noises they like to make. Oink! Spiky Shield A hedgehog’s back is covered with over 5000 spines or quills. They’re made of keratin, which is the same stuff human hair is made of! And just like humans, hedgehogs lose their spines and grow new ones over time. When in danger, a hedgehog will roll itself into a ball with all its spines sticking out to protect its soft underside. Gourmet Grub Hedgehogs are nocturnal, hunting for their food in the dark at night time. Although they have poor eyesight, they have excellent senses of smell and hearing, which they use to seek out food. Hedgehogs like to eat berries, grass and mushrooms, as well as frogs, snails, insects and even snakes and scorpions. Gross! Spiny Superstar Azuki is a pygmy hedgehog who lives in Japan.
