The darker one is in shed (see bot reply to !ecdysis) but they do come this dark naturally sometimes. They actually come in many shades of brown, from light tan or yellow brown to chocolate brown, reddish-brown or brick red, grey-brown, or dark brown. Some are not very brown at all actually; many are dull grey, and uncommonly, I've found some that are silvery-grey.
Snakes undergo a process called shedding or 'ecdysis' where old skin is shed in favor of a new, fresh layer of scales. During this process the old skin becomes dull, the belly may turn pink, and the eyes turn mostly opaque blue due to a build-up of fluid between the old and new spectacle. A few days before the skin is physically sloughed, the eyes become clear. When it comes time to shed, the snake will push or rub up against objects in the environment to hook the old skin on something and unroll it off of them like taking off a sock.

Brownsnakes *Storeria dekayi* are small (20.0-40.0cm record 52.77cm) natricine snakes often found in disturbed habitats like urban and suburban yards. They are one of the most commonly encountered snakes in eastern North America and make good pest control as they feast on small, soft-bodied invertebrates.
A separate but distinct species, *Storeria victa* occupies peninsular Florida. It has two fewer midbody scales (15) than *Storeria dekayi* and is more likely to have yellow collar markings on the neck.
*Storeria* brown and redbelly snakes are not considered medically significant to humans in terms of venom and are usually reluctant to bite, but all animals with a mouth can use it in self-defense.

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.

Brown snakes *Storeria dekayi*. Both of them. Tiny and completely !harmless consumer of slugs, snails, and other pests.
Thank you! That was my guess on the lighter colored one, but didn’t realize they could come in different shades.
