The Crotalus genus comprises a group of venomous pit vipers commonly known as rattlesnakes. These snakes are characterized by their distinctive rattle at the tail tip, which they use as a warning to potential predators. Widely distributed across the Americas, Crotalus species vary in size, coloration, and habitat but generally share traits such as heat-sensing pits and potent venom used for prey immobilization and digestion.
