Midland Water Snake (Nerodia sipedon pleuralis)STATUS





Description: Anteriorly, it has a pattern of dark crossbands on a light ground color. Posteriorly, the crossbands are replaced by three rows of alternating squarish blotches. The light spaces between the crossbands or blotches are wider than the dark markings. On the belly, the crescent-shaped markings on the ventrals tend to form two stripe-like series.

The maximum recorded total length for this subspecies is 51.5 inches. However, most adults are 22 to 40 inches in total length.


Habitat: This snake lives in wet habitats such as marshes, ponds, streams, and swales. In the Southern United States, it follows river valleys to the Gulf Coast.


Range: It is found in the central and southern United States, more specifically, in Alabama, northern Arkansas, northwestern Georgia, southern Illinois, southern Indiana, western Kentucky, southeastern Louisiana, Mississippi, southern Missouri, southeastern Oklahoma, northwestern South Carolina, and western and southeastern Tennessee.


Found in these States: AL | AR | FL | GA | IL | IN | KS | KY | LA | MO | MS | NC | OH | OK | SC | TN | TX


Diet: Nerodia sipedon pleuralis has a diet that is similar to other species of water snakes. Juvenile and small adults consume a variety of prey such as fishes, frogs, and salamanders. Adults consume primarily fishes.


Reproduction: Watersnake mates from April through June. It is ovoviviparous (live-bearing), which means it does not lay eggs like many other snakes. Instead, the mother carries the eggs inside her body and gives birth to free-living young, each one 7+1/2 to 9 inches long.A female may have as many as 30 young at a time, but the average is eight. They are born between August and October. Mothers do not care for their young. Multiple mating by females is common, leading to a focus in sperm competition. Research suggests successful males are not the ones who dedicate more energy to size, but to sperm.


Status: Listed as Least Concern in view of its wide distribution, tolerance of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
