Smooth Green Snake (Opheodrys vernalis) - Special Concern
Description: 11¾ - 20 inches. Smooth Green Snakes are usually bright green, but may rarely be tan. The belly is light yellow. Hatchling Smooth Green Snakes are darker in appearance and may be olive green, gray, or even blueish.
Similar Species: Smooth Green Snakes may be confused with Racers in pictures, but young Racers within the size range of Smooth Green Snakes will have a blotched appearance rather than being a solid color. Tan colored Smooth Green Snakes may be confused with Smooth Earth Snakes, but can be distinguished by the scales between the eyes and nostrils. A Smooth Green Snake will have one scale separating the scale around the nostril, and the scale in front of the eye. Smooth Earth Snakes have a scale behind the nostril that touches the scale in the front of the eye.
