1. Rattlesnakes belong from a group of venomous snakes known as Crotalus and Sisturus of Crotalinea (pit viper) subfamily. The word Sisturus is Latin form of Greek word, meaning Tail rattler.

2. Their rattle is made out of keratin like our hair and nails are made of. These are consist of several interlocking rings which are hollow, whenever they vibrate the rings knock with each other making the famous rattling sound.

3. Whenever snakes grow, they shed the old skin and go through molting process. The rattlesnakes also do the same but, their body naturally adds an extra ring of keratin on tail while shedding. Previously it was argued that rattlesnake age can be found by counting the rings. But scientists discovered the shedding is not constant for all of the snakes. Some rattlesnakes shed their skin 3 times a year whereas others can do twice depending on their growth. Hence, the rings can not tell their age.
