About the Eastern Diamondback Rattlesnake
The eastern diamondback rattlesnake (Crotalus adamanteus) is a species of pit viper in the family Viperidae. The species is endemic to the Southeastern United States. It is the largest rattlesnake species and one of the heaviest venomous snakes in the Americas. No subspecies are recognized.
The eastern diamondback rattlesnake is the largest rattlesnake species and is one of the heaviest known species of venomous snake, with one specimen shot in 1946 measuring 2.4 m (7.8 ft) in length and weighing 15.4 kg (34 lb). However, other venomous snakes may rival this species in weight such as the much longer but more slender king cobra and the shorter but even bulkier Gaboon viper. Maximum reported lengths for the eastern diamondback rattlesnake are 2.4 m (8 ft) and 2.5 m (8.25 ft). However, the stated maximum sizes have been called into question due to a lack of voucher specimens. Demonstrating rare reverse sexual size dimorphism, males are typically larger than females.
Specimens over 2.1 m (7 ft) are rare, but well documented. Klauber (1998) included a letter he received from E. Ross Allen in 1953, in which Allen explains how for years he offered a reward of $100, and later... Wikipedia →
