Nerodia paucimaculata, commonly known as the Concho water snake, is a species of mostly aquatic, nonvenomous snake in the family Colubridae. The species is endemic to Texas in the United States.
Nerodia paucimaculata is found only in west-central Texas in the Colorado and Concho river systems, in Coke, Runnels, San Saba, and Tom Green Counties.
Due to its limited range, N. paucimaculata was considered a threatened species in the state of Texas. [2]
Nerodia paucimaculata was originally considered to be a subspecies of the Brazos water snake, N. harteri , but was elevated to full species status by Densmore et al. in 1992. [3]
The Concho water snake grows to a total length (including tail) of 16 to 32 inches (41–81 cm), and looks very much like N. harteri. However, N. paucimaculata tends to be more red in color, and has no dark markings on the underside.
Nerodia is a genus of nonvenomous colubrid snakes commonly referred to as water snakes due to their aquatic behavior. The genus includes nine species, all native to North America. Five of the species have recognized subspecies.
Nerodia rhombifer, commonly known as the diamondback water snake, is a species of nonvenomous natricine colubrid endemic to the central United States and northern Mexico. There are three recognized subspecies of N. rhombifer, including the nominotypical subspecies.
Nerodia erythrogaster, also known as the plain-bellied water snake or plainbelly water snake, is a common species of semi-aquatic, non-venomous colubrid snake endemic to the United States.
The Florida cottonmouth is a species of venomous snake, a pit viper in the subfamily Crotalinae of the family Viperidae. The species is endemic to the United States, where it occurs in southern Georgia and the Florida peninsula in nearly every type of wetlands in the region, including brackish water and offshore islands. However, it is not entirely dependent on water and is occasionally encountered as far as a mile from surface water. Agkistrodon conanti venom is very hemolytic and known to cause relatively extensive necrosis compared to many snake venoms, and can sometimes be lethal with a 17% mortality rate. It is often confused with harmless watersnakes (Nerodia) and other semi-aquatic species with which it shares its habitat.
The Texas scarlet snake is a species of nonvenomous snake in the family Colubridae. The species is endemic to the South Central United States. It was previously considered a subspecies of Cemophora coccinea.
The Big Bend slider, also called commonly the Mexican Plateau slider and la jicotea de la meseta mexicana in Mexican Spanish, is a species of aquatic turtle in the family Emydidae. The species is native to the Southwestern United States and northern Mexico.
The Brazos water snake, also called commonly Harter's water snake, is a species of mostly aquatic, nonvenomous snake in the family Colubridae. The species is endemic to Texas in the United States.
The banded water snake or southern water snake is a species of mostly aquatic, nonvenomous, colubrid snakes most commonly found in the Midwest, Southeastern United States.
Nerodia clarkii, commonly known as the salt marsh snake, is a species of semi-aquatic, nonvenomous, colubrid snake found in the southeastern United States. Their range extends along the brackish salt marshes of the Gulf of Mexico and the Atlantic Coast from Texas to Florida, with an additional population in northern Cuba. Different subspecies of this snake are primarily identified via color patterns on each snake's belly, or anterior.
Regina grahamii, commonly known as Graham's crayfish snake, is a species of nonvenomous semiaquatic snake in the subfamily Natricinae of the family Colubridae. The species is endemic to the central United States.
The crayfish snake, also known commonly as the glossy crayfish snake, the glossy swampsnake, the glossy water snake, and the striped water snake, is a species of semiaquatic snake in the subfamily Natricinae of the family Colubridae. The species is endemic to the southeastern United States, and preys mainly on crayfish.

The green water snake is a common species of nonvenomous natricine snake endemic to the southeastern United States.
The brown water snake is a large species of nonvenomous natricine snake endemic to the southeastern United States. This snake is often one of the most abundant species of snakes found in rivers and streams of the southeastern United States, yet many aspects of its natural history are poorly known. Due to abundance and distribution throughout its biological range, this species could be used to investigate anthropogenic impacts on aquatic ecosystems by studying their movements.
The midland water snake, a subspecies of the northern water snake, is a nonvenomous natricine snake, which is endemic to North America.
Nerodia floridana, commonly known as the Florida green watersnake, or eastern green watersnake, is a harmless species of snake in the subfamily Natricinae of the family Colubridae. The species is native to the southeastern United States.
The common watersnake is a species of large, nonvenomous, common snake in the family Colubridae. The species is native to North America. It is frequently mistaken for the venomous cottonmouth.
