Eastern Diamondback Rattlesnake
Biome: Southern Swamps
Biography: This is the largest of all North American rattlesnakes and can reach lengths of 33-72 inches. It is found throughout the Everglades. These snakes hide beneath stumps and in holes in the ground during the day, coming out to feed on rabbits, mice, rats and birds at night. You will notice the "rattles" at the end of their tails. A new one is added each time the snake sheds its skin. But, since this happens more than once a year (2 to 4 times) and the end rattles often wear away or get broken, the number of rattles is a most unreliable way of judging the age of this reptile. Rattlesnakes rely on good eyesight and the information provided by their deep facial pits. These pits are located between the eyes and nostrils and can sense the heat given off by warm-blooded prey, which enables the rattlesnake to strike accurately at prey.
