Eastern diamondback rattlesnake
MordeThe eastern diamondback rattlesnake is a pit viper that lives in the southeastern United States. It is the largest rattlesnake species and one of the heaviest venomous snakes in the Americas. Its diamond-patterned back and loud rattle make it easy to recognise, and it is widely regarded as one of the most dangerous venomous snakes in North America.1

Its venom contains more than 100 different toxins, and about 40 have been identified, making it one of the most studied snake venoms.
