Crotalidae

Crotalidae is a family of venomous snakes commonly known as rattlesnakes, which are primarily found in the Americas. They are characterized by a distinctive rattle at the end of their tails, used as a warning signal. These snakes are highly adaptable and vary in size, with some species reaching over six feet long. Their venom contains enzymes and proteins that can immobilize and digest prey, and while bites can be serious, prompt medical treatment with antivenom is usually effective. Crotalidae snakes play an important role in controlling pest populations and maintaining ecological balance.
