Keep Herp Calendar free

Hi, I'm Nick. I built Herp Calendar on my own and I keep it free, with no ads. If it has helped you find a herp this season, a small tip goes straight into the hosting and the data work. Only if you can spare it. Either way, I'm glad you're here.

Look, don't take. Many states regulate collecting reptiles and amphibians. Photograph it, log it on iNaturalist and leave it where you found it.

Description

The brown water snake (Nerodia taxispilota) is a large species of nonvenomous natricine snake endemic to the southeastern United States. Dorsal scales are in 27–33 rows (more than any other North American water snake), and it has two to four anterior temporals (usually one in others).Wikipedia ↗

Habitat

Nerodia taxispilota is found in lower coastal regions from southeastern Virginia, through North Carolina, South Carolina, and Georgia, to northern and western Florida (Gulf Coast), then west through Alabama, and Mississippi, to Louisiana, normally from sea level to 500 ft. (150 m) elevation. Nerodia taxispilota is found in swamps and streams and is often mistaken for a moccasin.Wikipedia ↗

When it's active

Often mistaken for

Northern Cottonmouth, Florida CottonmouthMany scientists dislike the use of the term water moccasin since it can lead to confusion between the venomous cottonmouth and nonvenomous water snakes. Wikipedia ↗Nerodia fasciata is often mistaken for venomous cottonmouths (Agkistrodon piscivorous) despite the differences in their physical appearance.
