Timber rattlesnake

The timber rattlesnake (Crotalus horridus), also known commonly as the banded rattlesnake, and the canebrake rattlesnake in the southern United States, is a species of pit viper in the familyViperidae. The species is native to the eastern United States. Like all other pit vipers, it is venomous, with a very toxic bite. Its venom is extremely potent, and both hemorrhagic and neurotoxic venom are present depending on population and location. C. horridus is the only rattlesnake species in most of the populous Northeastern United States and is one of the most northerly distributed venomous snakes in North America. There are no subspecies that are recognized as being valid.
