Two families of venomous snakes are native to the United States. The vast majority are pit vipers, of the family Crotalidae, which include rattlesnakes, copperheads and cottonmouths. Virtually all of the venomous bites in this country are from pit vipers. Some, Mojave rattlesnakes or canebrake rattlesnakes, for example, carry a neurotoxic venom that can affect the brain or spinal cord.
Copperheads, on the other hand, have a milder and less dangerous venom that sometimes may not require antivenin treatment.....
