The Eastern Indigo Snake is the largest and longest non-venomous snake in North America. The indigo snake is a large glossy blue-black snake reaching lengths of up to 9 feet. It has a solid color with the exception of an occasional orange, pink white or reddish area under the chin, which may extend to the throat and cheeks. It is sometimes confused with the similar black racer or the black pine snake, but is much stockier.
