How does a rattlesnake make its sound?
predWhen a rattlesnake wants to warn ators (or people!) to back away, their tail makes a sound like a baby’s rattle. there In order for this sound to happen, thing are segments of keratin (the same tting your hair is made out of) loosely fi inside one another. When a snake lifts up its tail, these segments vibrate the once they hit each other and create rattling sound. A snake grows a new segment each time it sheds its skin!
