This is the only Garter Snake in Ohio with the side stripes confined to the 2nd and 3rd rows of scales. However, on some individual snakes the stripes may be of a darker color (brownish, greenish or bluish) and very difficult to see. The scales are keeled and the anal plate is single.

Local Habitat
Wet woodlands, meadows, marshes and along drainage ditches and streams.

This is the most widely distributed snake in North America. Also, in many parts of its range it is the snake most commonly encountered by people. This diurnal snake generally lives in moist areas where it finds food. It becomes aggressive when confronted by people and generally will try to bite and often it will expel foul-smelling musk onto its tormentor.
During cold weather the Eastern Garter Snake hibernates in community dens with large numbers of other individuals.
