Rattlesnakes feed on small mammals and reptiles. Like most pit vipers, they give birth from eggs hatched inside the
It has forked tongue. The snake uses this to "taste" the air and find its prey. Pit vipers, like the diamondback,
also use heat sensitive areas in "pits" on the front of their heads to locate their victims even in total darkness.
Rattle snakes are recognized by a loose, horny rattle at the end of the tail, which is shaken vigorously to
warn off intruders. The rattle is formed when the snake’s skin is shed, the end section of the rattle and an attached
ring of the old skin are retained on molting. A new ring is added each time the snake molts, which may be as often as four
times a year. The last ring on the rattle often becomes worn and breaks off, so that the number of rattles is not, as popularly
believed, an accurate indication of age of the snake
