Are Porcupines Quills Barbed at Natalie Rebecca blog

Are Porcupines Quills Barbed. Barbs render a quill about four times harder to pull out once they’re embedded, the team found. North american porcupines have around 30,000 quills on their backs. Small, sharp barbs on the end of each quill will stick into the predator and release from the porcupine. The researchers took barbed porcupine quills and plunged them into samples of pig skin, measuring how much force it took to pierce the flesh and then how much force was required to extricate the quill. Not so for the victim though. Both adults and porcupettes shed quills naturally, but they always grow. Quills are loosely held by a porcupine's skin, and so if another creature comes into contact with a porcupine, quills detach easily from the porcupine. The barbed quills also slide in with less force than a hypodermic needle of the same width, or than the quill of an african porcupine, which doesn’t have any barbs (see end of. The team then performed the same tests using quills whose barbs they had sanded off. Computer models suggest that the barbs ease the quill’s penetration by concentrating force along the edges of the barbs, similar to how the serrations on a knife blade make cutting meat easier.
