No, rattlesnakes don’t shed their rattles.
When a rattlesnake sheds its skin, a new rattle segment forms, allowing its iconic buzz to grow louder with each molt.
The rattle is composed of hollow, interlocked keratin segments that vibrate when the tail muscles contract.
With age, the rattle gradually gains segments, though its size can vary across species and regions.
So if you hear that unmistakable sound, it’s best to give the rattler a wide berth – it’s just trying to avoid a painful encounter for you both.
