  • Hedgehog quills are actually modified hairs made of keratin like our own hair.
  • On average there are about 5,000 to 6,500 of these quills.  Hedgehogs cannot release their quills like a porcupine can.
  • These animals have some natural immunity against snake venom due to a protein in the muscular system.
