The Copperhead (Agkistrodon contortrix) is by far the most wide spread venomous snake of Georgia (and the U.S.). They can be found ALL over Georgia (except some southern counties bordering Florida). There are five sub-species of copperhead (3 are in Georgia); Since many share overlapping territories they will often cross breed. It is more likely to find one with traits from several sub-species. The good news is that all Georgia's copperheads are close enough in appearance. If you can learn to identify one, you can easily identify all.
