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.
It is common to find snakes on the road in the evening hours as they attempt to warm their bodies by lying on asphalt or concrete paved areas. Life Cycle of Rattlesnakes: While some types of snakes lay eggs, a rattlesnake's young are born alive.attlesnakes do not have outer ears and therefore rely on these vibrations to pick up sound. The snake's eyes can detect objects or movement from about 40 feet away, but its vision is much sharper when objects are closer. A rattlesnake's pupils are elliptical, not round, which enables the snake to see well in dim light.
