Canada Porcupine is a unique species of porcupine that is found only in North America. There are many different synonyms for this fascinating creature, including quill pig, hedgehog, spiny rat, and porcu. These names all refer to the Canada Porcupine's most striking trait: its quills. These long, sharp spines cover its body and serve as a defense mechanism against predators. Interestingly, these quills are actually modified hairs, and can be easily released from the porcupine's skin to stick into the predator. Despite its formidable appearance, the Canada Porcupine is a docile and solitary creature that primarily feeds on trees and other vegetation.
