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. Description 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 in length and weighing . 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 and . However, the stated maximum sizes have been called into question due to a lack of voucher specimens.

Ventral Scales
In snakes, the ventral scales or gastrosteges are the enlarged and transversely elongated scales that extend down the underside of the body from the neck to the anal scale. When counting them, the first is the anteriormost ventral scale that contacts the paraventral (lowermost) row of dorsal scales on either side. The anal scale is not counted.Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishing Associates, Ithaca and London. 870 pp. 1500 plates. . The term gastrostege (from Greek γαστήρ, γαστρός = belly and στέγη, στέγος = cover, roof) was more often used in the older literature, especially pre-1900 but is rarely used today.

Dorsal Scales
In snakes, the dorsal scales are the longitudinal series of plates that encircle the body, but do not include the ventral scales. Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 2 volumes. 870 pp. 1,500 plates. . When counting dorsal scales, numbers are often given for three points along the body, for example 19:21:17. These numbers correspond to the number of dorsal scales around the body at a head's length behind the head, at midbody and at a head's length before the vent. If only one number is given, it is for the midbody count. Dorsal scale are easiest to count diagonally, starting with the paraventral scale row. In doing so, it is often noted that certain scale rows are raised, keeled or smooth as opposed to the others.U.S. Navy (1991). ''Poisonous Snakes of the World''. United States Government. New York: Dover Publications Inc. 203 pp. . See also *Snake scales *Anatomical terms of locat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
