ScanSolve AI Answer

Here are three differences between a porcupine and a hedgehog:

  • Size: Porcupines are significantly larger than hedgehogs.
  • Quills/Spines: Porcupine quills are long, sharp, and can detach easily, while hedgehog spines are shorter, less sharp, and are firmly attached.
  • Defense Mechanism: Hedgehogs typically roll into a tight ball for defense, whereas porcupines primarily use their quills by shaking them or backing into predators.
