Thamnophis sauritus, commonly known as the Eastern Ribbon Snake, is a slender, semi-aquatic serpent prevalent in wetlands and marshes across eastern North America. It is distinguished by its long, thin body, vivid stripes running along its length, and an affinity for basking near water bodies where it hunts amphibians and small fish.

Thamnophis sauritus, commonly known as the Eastern Ribbon Snake, is native to the eastern United States and southeastern Canada. Its geographical distribution includes the northeastern United States, the Great Lakes region, and extends southward to parts of the southeastern United States.

The Eastern Ribbon Snake is typically found in wetland environments, including marshes, swamps, and the edges of ponds and streams. It prefers areas with abundant vegetation that provides cover and hunting grounds. The climate in these regions ranges from temperate to subtropical, with seasonal variations in temperature and precipitation.

Thamnophis sauritus occupies an ecological niche as both predator and prey within its habitat. It primarily feeds on amphibians, small fish, and invertebrates, using its aquatic and terrestrial agility to capture prey. The species is well-adapted to its wetland habitat, exhibiting behaviors and physical adaptations suited to both water and land environments.
