Hedgehogs look kind of like tiny little porcupines.

And just like porcupines, they have poky hairs on their back (called spines) made of keratin.

Their spines don't come out like a porcupine's quills, they are just sharp.

(from: wikipedia - hedgehog)

Hedgehogs also do a funny thing called anointing.
When they find something with a new smell in the wild,
they will lick and bite that thing, and then spit on their spines.

Scientists aren't totally sure why they do this,
but some think it is so they can hide their smell from other animals that want to eat them!
