On a walk through I’ON Swamp/Natural Forest in Mt. Pleasant, SC, we came upon this snake. We did not get too close for fear it may be poisonous.

It had a very dark brown/taupe exterior with almost a diamond shaped head. It had a reddish, orange belly. It was ~3-4’ in length and fairly large girth.

  • $\begingroup$ there is a Yellow Belly Water snake here in TX that the book says is the same as a Red Belly Water snake in the east. Looks like a good possibility. $\endgroup$ Commented Apr 21, 2020 at 0:57

Hard to tell without a clearer picture, but the size and color pattern seem to match the description for the Plain-bellied Watersnake.

See for example the following picture from the Virginia Herpetological Society: enter image description here

I assume from the location being in something called a swamp that the habitat (in and near slow moving bodies of water) also fits.

  • $\begingroup$ That’s it! That’s the same snake we saw on the trail. Thank you! $\endgroup$
