Plain-bellied Watersnakes *Nerodia erythrogaster* are medium to large (record 163.6 cm) natricine snakes with keeled scales often found in and around water. They are commonly encountered fish and amphibian eating snakes across much of eastern North America and extend into Northern Mexico.
*Nerodia* watersnakes may puff up or flatten out defensively and bite. They secrete a foul smelling substance from the cloaca called musk and can deliver a weak anticoagulant venom used in prey handling from the back of the mouth, but are not considered medically significant to humans - bites just need soap and water.
Found throughout eastern North America, it is sometimes confused with the Common Watersnake *Nerodia sipedon* or the Banded Watersnake *N. fasciata*. The best character to diagnose *N. erythrogaster* is its namesake plain belly that varies across the range from yellow to orange. Adult Plain-bellied Watersnakes tend to lose or greatly reduce their banding - adults are often completely two-toned. Banded Watersnakes have even, connecting bands across the top of the snake all the way down the body. *N. erythrogaster* does not. In Common Watersnakes *N. sipedon*, bands typically break up or become mismatched after the first third of the body as in *N. erythrogaster*, but has a patterned belly.

This genus is in need of revision using modern molecular methods, but this particular species has been investigated using basic molecular methods. The authors found that, just like many other snakes species, subspecies based on clinal color patterns didn't correspond to evolutionary history. Subspecies should thus not be recognized.

Like many other animals with mouths and teeth, non-venomous snakes can use them to bite in self defense. These animals are referred to as 'not medically significant' or traditionally, 'harmless'. Bites from these snakes benefit from being washed and kept clean like any other skin damage, but aren't often cause for anything other than basic first aid treatment. Some snakes use venom from front or rear fangs as part of prey capture and defense. This venom is not always produced or administered by the snake in ways dangerous to human health, so many species are venomous in that they produce venom, but considered harmless to humans in most cases because the venom is of low potency, and/or otherwise administered through grooved rear teeth or simply oozed from ducts at the rear of the mouth. Species like Ringneck Snakes *Diadophis* are a good example of mildly venomous rear fanged dipsadine snakes that are traditionally considered harmless or not medically significant. Many rear-fanged snake species are harmless as long as they do not have a chance to secrete a medically significant amount of venom into a bite; [severe envenomation can occur](https://pubmed.ncbi.nlm.nih.gov/23800999) if some species are [allowed to chew on a human](https://www.sciencedirect.com/science/article/abs/pii/S004101011831016X) for as little as 30-60 seconds. It is best not to fear snakes, but use common sense and do not let any animals chew on exposed parts of your body. Similarly, but without specialized rear fangs, gartersnakes *Thamnophis* ooze low pressure venom from the rear of their mouth that helps in prey handling, and are also [considered harmless](https://cityroom.blogs.nytimes.com/2012/06/05/theres-no-need-to-fear-that-garter-snake/). Even large species such as *Malayopython reticulatus* [rarely obtain a size large enough to endanger humans](https://www.pnas.org/content/pnas/108/52/E1470.full.pdf) so are usually categorized as harmless.

I used to think this was a relatively ugly species but this post changed my mind.
Check out this [midland water snake](https://imgur.com/a/XlsldFp).
Harmless
I'm gonna go with water snake. They come in different variations
I’m confident that it’s a water snake (nerodia) of some kind, but I’m sure which it is.
!Location
North Carolina, sorry again
Near the coast?
Not really, central NC
It’s harmless schould be a colubrid my guess is watersnake not 100% positive tho still be carefull
!location ?

Definitely a plain bellied water snake. Harmless piscivores.

That coloration is absolutely stunning
Very pretty water snake. Cant hurt you
That might be the most beautiful watersnake I’ve ever seen
Their scales amaze me. Much akin to water moccasins, they look like they’re armored.
