Rattlesnake Biology. Rattlesnake Biology. Rattlesnakes are usually identified by their warning rattle (a hiss or buzz) made by the rattles at the tip of their tails. A rattlesnake is born with a button, or rattler, and acquires a new rattle section each time it molts. Rattlesnakes also are distinguished by having rather flattened, triangular heads.
They are one of the most iconic groups of North American snakes due to the characteristic ârattleâ found at the tip of the tail. The rattle is composed of a series of interlocking scales, which are added to each time the snake molts. Muscle contractions cause the scales to click together, resulting in the rattle sound. Size: A number of different rattlesnakes live in the United States, and they range in size from the 1 foot long ridge-nosed rattlesnake to the 5 to 8 foot long eastern diamondback. Diet: Rattlesnakes are pit vipersâthey have heat sensing organs located in pits near the eyes.
