The Fascinating World of Porcupines
Porcupines are unique rodents known for their sharp quills, derived from the Latin term meaning 'thorn pig.' In North America, porcupines belong to the Erethizontidae family, with about 20 species, while the Old World versions are categorized in the Hystricidae family. Their quills, which can number around 30,000, are modified hairs that feature barbs, making removal difficult once embedded in skin. These barbed quills serve as a defense mechanism against predators, reinforcing the idea that these creatures are more than just their prickly exteriors.
