Join us as we explore the remarkable world of animals similar to porcupines.

Key Takeaways

  • Hedgehogs are similar to porcupines in that they have quills on their backs for protection.
  • Ringtails also have quills on their backs, but they are smaller and spikier than those of porcupines.
  • Echidnas have spiky quills on their heads and tails, similar to porcupines, but they are used for protection rather than as a defensive mechanism.
  • Spotted hyenas and mongooses have long, spiky hairs on their bodies that serve as a defense mechanism, although they are not true quills like porcupines have.


If you frequently encounter quilled mammals, you may be familiar with hedgehogs. Hedgehogs are insectivorous mammals that have unique features in their quills. When comparing them to other insectivorous mammals, such as echidnas and ringtails, hedgehogs stand out for their solid spikes on their backs. Unlike the hollow tubes found on porcupines, hedgehog quills are solid, providing them with a formidable defense against predators.

The quills of hedgehogs are specially adapted for protection. They consist of keratin, the same material found in our hair and nails, giving them strength and flexibility. Each quill is covered in sharp, barbed tips, which make it difficult for predators to remove them once they become embedded in their skin. When threatened, hedgehogs will curl into a tight ball, exposing only their quills to deter predators.

The quills of hedgehogs also serve as a means of communication. When interacting with other hedgehogs, they may raise and lower their quills to convey different messages. For example, when feeling threatened, hedgehogs will stand their quills up to appear larger and more intimidating.


Ringtails are small, hairy, insectivorous mammals found throughout Australia. They are known for their unique behaviors and their distinctive defense mechanisms. Let’s compare the defenses of ringtails with those of spiky-haired carnivores.

RingtailsSpiky-haired Carnivores
