Nerodia clarkii clarkii, the Gulf salt marsh snake, is a subspecies of N. clarkii that is indigenous to the south-eastern United States. It is a nonvenomous, colubrid snake that inhabits coastal salt marshes and brackish estuaries along the coast of the Gulf of Mexico from Florida to Texas.[1][2]

Description

The Gulf salt marsh snake is a moderately stout aquatic snake.[1] Adult specimens attain an average total length (including tail) of 38 to 51 cm (15 to 20 in), with the record maximum total length at 91.4 cm (36.0 in).[2] The color pattern in this subspecies is variable, but adults tend to have a dorsum that ranges from dark gray to reddish-brown with four yellowish longitudinal stripes down the body, two on each side. The belly is dark gray to reddish-brown with one to three rows of pale spots.[1][2]

Reproduction

The Gulf salt marsh snake reaches sexual maturity at three years. Females give birth to 2-44 live young that range from 17.7 to 22.8 centimetres (7.0 to 9.0 in) in total length. Their typical lifespan is up to 20 years.[1][2]

Diet

N. c. clarkii is primarily nocturnal, preying upon small fish, crabs, shrimp, and other invertebrates that become trapped in tidal pools during low tide.[1][2]
