Rainbow Freckled Snakes Make For Unique Pets - This has to be one of the coolest corn snake morphs I've ever seen. Corn snakes, along with other types of captive snake species, can come in a multitude of morphs based on selective breeding. In this case, however, a wild caught corn snake displaying this morph was found in South Carolina in 2008. That's where it gets its name from - the Palmetto Corn Snake (Pantherophis guttatus), after the Palmetto State (South Carolina).
