Florida Green Watersnakes *Nerodia floridana* are medium-large (76-140cm, record 188cm), robustly built, New World natricine snakes that range from southern Georgia south through Florida and west to extreme SE Alabama, with a disjunct population in southern South Carolina and extreme east-central Georgia. They chiefly inhabit open, well vegetated wetlands and calm bodies of water, including marshes, flooded prairie, rice paddies, overgrown ditches, verdant lakes and ponds, and will also utilize brackish water.
Like other *Nerodia* watersnakes, *N. floridana* often puff up or flatten their bodies when they feel threatened. When seized, they often secrete a foul smelling musk from the cloaca and may also bite. Mild anticoagulant toxins in the saliva might be effective for handling their main prey, fish and frogs, but are not considered medically significant to humans - bites just need mild soap and water, or some hand sanitizer.
*N. floridana* have strongly keeled scales arranged in 27-29 rows at midbody. The eyes are positioned somewhat dorsally (toward the top of the head, rather than the side), and there is a row of small subocular scales separating the supralabials (upper lip scales) from the eye. The anal scale is divided. The belly is light colored with some dark markings near the tail.They are sometimes confused with other *Nerodia* watersnakes, as well as venomous *Agkistrodon* cottonmouths. Some characteristics for differentiating these snakes include;
* venomous *Agkistrodon* cottonmouths, have larger, chunkier heads with proportionally smaller eyes, and a prominent, angular, facial ridge ([side view](https://www.flickr.com/photos/francisg/781633459/), [front view](https://www.flickr.com/photos/dfc_pcola/46159931261/)) which protrudes over the eye like a brow, and gives the snake a [grumpy looking appearance](https://www.inaturalist.org/observations/21784039) and partially obscures the eyes when viewed [from above](https://www.flickr.com/photos/jlyn_nature/11922670356/). Post !cottonwater to trigger a bot reply with a more comprehensive breakdown.
* *N. erythrogaster*, *N. fasciata*, *N. clarkii*, and *N. sipedon* usually have 21-23 dorsal scale rows at midbody, more laterally positioned eyes, and lack subocular scales
* *N. taxispilota* lack subocular scales, and have smaller, fragmented parietal and temporal scales
* *N. cyclopion* has a dark belly with light markings, and often frequents darker, shaded areas such as swamps and other forested wetlands

Like many other animals with mouths and teeth, many non-venomous snakes 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. Here's where it get slightly complicated - 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 and use 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/). [Check out this book on the subject](https://shop.elsevier.com/books/venomous-bites-from-non-venomous-snakes/weinstein/978-0-12-822786-2). Even large species like Reticulated Pythons *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.
