How do porcupine quills work? Meet Guillermo, a prehensile-tailed porcupine from South America. His most powerful tool is his natural armor. Guillermo's quills lie flat until he senses danger, then flex up to deliver a sharp surprise. Each quill is covered in tiny, backward-facing barbs, designed to embed like a fishhook and resist removal. This clever structure makes porcupine quills one of nature’s most effective defense mechanisms. #Animals #Porcupine #Biology #Wildlife #Science | Museum of S
