Lined Snake Tropidoclonion lineatum - Special Concern

Description: 8 - 15 inches. Lined Snakes are gray or brown, with a light colored stripe down the center of the back, as well as one down each side on the second and third row of scales. These stripes on the side may blend in with the color of the scales on the belly (ventral scales) making them hard to distinguish. The belly is light colored with two rows of dark half-moon shaped markings.

Similar Species: Common Garter Snakes and Plains Garter Snakes are usually less uniform in appearance, and have black markings on the lips. Both garter snakes lack the double row of half-moons on the belly.

Comments: Restricted to a single area in Rock County, Minnesota. Please report sightings of this species!
