[Note Guidelines] Photographer's Note
Rattlesnakes are a group of venomous snakes that belong to the class of venomous snakes known commonly as pit vipers. They receive their name for the rattle located at the tip of their tails. The rattle is used as a warning device when threatened.

The rattle is composed of a series of nested, hollow beads which are actually modified scales from the tail tip. Each time the snake sheds its skin, a new rattle segment is added. They may shed their skins several times a year depending on food supply and growth rates. The rattle may break; there is little truth to the claim that one can tell a rattlesnake's age from the number of beads in its rattle. Newborn rattlesnakes do not have functional rattles; it isn't until after they have shed their skin for the first time that they gain an additional bead, which beats against the first bead, known as the button, to create the rattling sound. Adult snakes may lose their rattles on occasion, but more appear at each molting. If the rattle absorbs enough water in wet weather, it will not make noise.

This particular snake was a Diamondback Rattlesnake. Picture taken at the Houston Zoo.
