Classification

Quills are modified hairs that aren't very sharp.
Quills are filled with soft air pockets and have a hard cover.
Two large muscles on both sides of a hedgehog's back are used to raise and lower quills and help them curl into a ball.
This is a hedgehog's only defense.

Quilling is the stage in a young hedgehog where they begin to shed their baby quills and grow adult quills.
Quling usually starts at 8 weeks of age and last for 12 weeks.
Hedgehogs have an average of 5,000-7,000 quills.
