Porcupine Quill Distance at Marjorie Hubbard blog

Porcupine Quill Distance. Porcupines can’t shoot their quills like arrows over long distances, or aim them at a particular target like another animal or a human that gets too close. To the scientists’ surprise, barbed quills required approximately half the penetration force of the barbless quills—either those naturally barbless or those sanded clean—and only 56% of the force needed for the hypodermic needle to breach the skin. Despite their prickly reputation, porcupines are. While porcupines cannot shoot their quills with force or accuracy, the distance they can travel depends on the proximity to the porcupine and the force of the predator’s contact. Porcupines have soft hair, but on their back, sides, and tail it is usually mixed with sharp quills. Porcupines can have up to 30,000 quills on their bodies, and they use them not only for defense but also for communication and climbing. Some quills, like those of africa's crested porcupine, are nearly a foot long. However, if a porcupine feels threatened, the animal will expose its quills as a method of protection and defense. When a porcupine chooses to fight its adversary rather than flee, it quickly jumps at its opponent, often skewering it with those. The anatomy of porcupine quills
