Yes. The spines are hollow hairs made stiff with keratin (structural proteins). They aren't poisonous or anything, but they are sharp.
Hedgehogs are very cute and when small have a round snout and white or brown fur. They have spines on their backs.
No, unlike porcupines, they have hollow tubes on their back.Hedgehogs are easily recognized by their spines, which are hollow hairs made stiff with keratin. Their spines are NOT poisonous or barbed and, unlike the quills of a porcupine, cannot easily be removed from the hedgehog. However, spines normally come out when a hedgehog sheds baby spines and replaces them with adult spines. This is called "guiling" When under extreme stress or during sickness, a hedgehog can also lose spines.
