About Thamnophis proximus (Say, 1823)
Thamnophis proximus is a slender snake with a very long tail that makes up approximately one-third of its total body length. Its dorsal surface is blackish, brown, or olive, marked with three light-colored stripes. Its ventral surface is greenish-white or yellowish-white. The upper labial scales are whitish and unmarked, which contrasts with the dark top and sides of the head. The species-specific epithet proximus refers to this species' close similarity to Thamnophis saurita. Fully grown individuals reach a total length of 17 to 50 inches (43 to 127 cm), including the tail. Ecologically, Thamnophis proximus is a semiaquatic snake that occupies a wide variety of habitats, typically staying not far from water. It occurs at elevations ranging from sea level to nearly 2,500 m (8,200 ft). It feeds on a diverse range of prey, including invertebrates such as earthworms and crayfish, and small vertebrates such as lizards, fish, and frogs (including tadpoles).
