Oklahoma, and east Texas. For example, contortrostatin, a derivative of copperhead venom, has been suggested to have anti-cancer properties by limiting metastasis and blood vessel development within a tumor. Missouri has two subspecies of eastern copperhead: The Osage copperhead (Agkistrodon contortrix phaeogaster), found in the northern two-thirds of the state, and the southern copperhead (Agkistrodon contortrix contortrix) in the southern third. In the Piedmont, the two subspecies overlap in distribution, and specimens take on a range of appearances falling between the typicalpatterns for each subspecies.

Male sperm storage also occurs, as sperm are retained in the male epididymes (in mammals) for a period that can, in some cases, extend over several weeks or more, but here we use the term to refer only to sperm storage by females. Recent molecular analyses using mitochondrial DNA however suggests that there are three clades within the species that have relatively low divergence and do not correspond to the above-mentioned subspecies designations.
