Old World porcupine

The Old World porcupine, belonging to the family Hystricidae, is a type of rodent characterized by its quills. These porcupines are generally terrestrial, though some species can climb. They are known for their short tails and bulky bodies. Unlike New World porcupines, Old World porcupines have quills embedded in clusters. Their quills are modified hairs that detach easily when threatened, serving as a defense mechanism. While they cannot throw their quills, they can erect them into a crest. Their coloration varies, often with bands of white, yellow, orange, or black on their spines, creating a variegated pattern over a base of grayish brown to blackish.12
