Rattlesnakes are large, venomous snakes that are found throughout North and South America. The greatest concentration of them is in the Southwestern United States and in Northern Mexico. Arizona is home to 13 species of rattler, more than any other state. The most distinctive feature that these species share is the rattle.
Residents of the Southwestern United States likely have heard the distinctive buzz of these pit vipers. Their namesake rattle is a highly effective warning sign, signaling predators to stay away. “Rattles are segments of keratin that fit loosely inside one another at the end of the snake’s tail,” explained Sara Viernum, a herpetologist based in Madison, Wisconsin. “These segments knock against each other to produce a buzzing sound when the snake holds its tail vertically and vibrates the rattle. Each time a rattlesnake sheds its skin it adds another segment to the rattle.”
Scientists consider the rattlesnake’s rattle a highly evolved and sophisticated warning system — which makes sense since, according to the San Diego Zoo, these are the newest and most evolved snakes in the world.
