Atlantic Marsh Snake

Nerodia clarkii taeniata

Status: Native; Threatened

Most adult Saltmarsh Snakes are about 15-30 inches (38-76 cm) in total length. Color patterns of these snakes are extremely variable. Adults can be gray, grayish-olive, brown, tan, or rusty orange, with variable patterns of dark stripes or bands down the body. However, some individuals may lack stripes entirely, and some individuals may be almost entirely black. Juvenile coloration is similar to that described for adults. Saltmarsh Snakes are not dangerous to people or pets, but they may bite to defend themselves. These secretive and generally docile snakes are not aggressive and avoid direct contact with people and pets. Virtually all bites occur when the snakes are intentionally molested. They can be distinguished from black racers, which are bluish black from head to tail.
