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.
Rattlesnakes, water moccasins (âcottonmouthsâ), and copperheads are reptiles of the family Viperidae, subfamily Crotalinae (formerly Crotalidae), which consists of 18 genera and 151 species. Crotilinae are responsible for most of the 5,000 snake bites reported annually in the United States.
