The Western Diamondback Rattlesnake, Crotalus atrox, is a species of venomous rattlesnake found in the United States and Mexico. It is found in California, Arizona, New Mexico, Oklahoma and Texas. It prefers flatlands and prairies to the rocky hills and low mountains. This snake is generally colored dark or light brown. Its pattern is a unique row of large, dark diamond shapes edged in yellow trim, running down the length of its body. The diamonds fade to dark rings around the tail, where...
Rattlesnakes are a group of venomous New World snakes (genera Crotalus and Sistrurus) which have a small jointed rattle on their tails. They use this rattle as a warning device when they feel 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. Since they may shed their skins many times a year (depending on food supply and consequent growth rates), and...
