Geographic range
It is found only in west-central Texas in the Colorado and Concho river systems, in Coke, Runnels, San Saba, and Tom Green counties.
Conservation status
Due to its limited range, it was considered a threatened species in the state of Texas.[1]
Taxonomy
It was once considered to be a subspecies of the Brazos water snake, Nerodia harteri, but was elevated to full species status by Densmore et al. in 1992.[2]
Description
The Concho water snake grows from 16 to 32 inches (41-81 cm), and looks very much like Nerodia harteri, but tends to be more red in color and has no dark markings on the underside.
