Description

The Southern water snake grows from 24 inches (61 cm) to 48 inches (120 cm), and is typically gray, green-gray or brown in color with dark cross-banding. Many specimens are so dark in color their patterning is barely discernible. They have a flat head, and are fairly heavy bodied. Their appearance leads them to be frequently mistaken for other snakes with which they share a habitat, including the less common cottonmouth.

Reproduction

The species is ovoviviparous.

Subspecies

There are three recognized subspecies of N. fasciata:

Taxonomy
