Description: Rattlesnakes are highly specialized, venomous reptiles with large bodies and triangle-shaped 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.
