Eastern diamondback rattlesnakes (Crotalus adamanteus) are venomous snakes native to the southeastern United States. They are one of the largest and most venomous rattlesnakes in the world, and their bites can be fatal if not treated promptly.
Eastern diamondback rattlesnakes are typically found in pine forests, swamps, and other moist habitats. They are ambush predators, and they typically prey on small mammals, birds, and reptiles. Eastern diamondback rattlesnakes are also known to be cannibalistic, and they will sometimes eat other snakes of the same species.
