Eastern diamondback rattlesnake
"C. adamanteus" is the largest rattlesnake species and is the heaviest known species of venomous snake, with one specimen shot in 1946 measuring in length and weighing . However, other venomous snakes may rival this species in weight. The much longer but more slender king cobra is probably greater in average body mass if not maximum weight, and the shorter but even bulkier Gaboon viper could (but is not verified to) exceed the eastern diamondback rattlesnake in both mean adult body mass and possibly even maximum body mass. Maximum reported lengths for the eastern diamondback rattlesnake are and . However, the stated maximum sizes have been called into question due to a lack of voucher specimens. Males are larger than females.
