Western pygmy rattlesnake (Sistrurus miliarius streckeri), Wayne County, Missouri (13 April 2018) S. miliarius is a small species but bulky when it comes to width, [5] with adults usually growing to 40–60 cm (16–24 in) in total length (including tail). The maximum reported total length is 78.8 cm (31.0 in) (Klauber, 1972).

Timber rattlesnake, Crotalus horridus This is a list of all sure genera, species and subspecies of the subfamily Crotalinae, [1] otherwise referred to as crotalines, pit vipers, or pitvipers, and including rattlesnakes Crotalus and Sistrurus.
Sistrurus species differ from the larger rattlesnakes of the genus Crotalus in a number of ways. They are smaller in size, but also their scalation is different: Sistrurus species have nine large head plates (same as Agkistrodon), whereas in Crotalus (and almost all other viperids), the head is mostly covered with a large number of smaller scales.
No species of Crotalus is considered aggressive; when threatened, most retreat quickly, but most species defend themselves readily when cornered. [3] There is no consensus in the available literature about how far rattlesnakes can strike, with estimates ranging from one-third to the entire body length of the rattlesnake.
The Osage copperhead (Agkistrodon contortrix phaeogaster) was once classified as a subspecies of the copperhead (Agkistrodon contortrix).However, DNA based studies published in 2008 and 2015, revealed no significant genetic difference between the Osage copperhead (Agkistrodon contortrix phaeogaster), the southern copperhead, (Agkistrodon contortrix contortrix), and the northern copperhead ...
