Status:

Eastern Ribbonsnake (Thamnophis saurita) is a semi-aquatic garter snake tends to be found along vegetated pond or lake edges, around vernal pools, or in marshes, swamps, or wet meadows. It is closely associated with margins of wetlands, where it usually hunts small fish or amphibians, especially anurans (Tennant, 2003). In Maryland, Eastern Ribbonsnake is distributed statewide, but appears to be less common in western Maryland (Maryland DNR).

Description:

Eastern Ribbonsnake (Thamnophis saurita) can be distinguished from the ubiquitous Common Gartersnake by its more slender body shape and proportionately longer tail (29.8-38.8% of total BL). Ribbonsnakes show a distinctive pale patch on the preocular scale, anterior to the eyes, and lack dark sutural markings on the labial scales. There is a maximum of 19 total dorsal scale rows, and the lateral stripes occupy dorsal scale rows 3-4 on each side (Rossman et al., 1996).

There are 85 records in the project database.
