Eastern Garter Snakes are some of the hardest snakes to classify as a morph because the normal coloration has a VERY EXTREMELY WIDE RANGE!!! I once caught a garter snake that was literally a hot pink color. But she was still a normal. If you TRULY believe that this is a morph, you should get a standard normal, breed the 2 together, and breed the babies together. If the 3rd generation babies come out looking like this snake, you have a morph, if they come out looking normal, you have a nicely colored snake. Remember, it is very hard almost impossible to claim a morph in an eastern garter that has not been proven out through breeding. Hope this helps!
