Description

Nerodia cyclopion is a large, harmless fish-eaters native to coastal Mississippi and along parts of the Mississippi River delta. They can be found in coastal meadows, swamps, and marshes. Unique to this species is the green coloration in conjunction with a subocular scale. Belly is brown with lighter markings or half-moons. Scales are strongly keeled, as they are in all Nerodia. Adults may reach lengths of up to 4 feet (Powell et al., 2016). This species is exclusively found in the coastal counties. They primarily eat fish.
