The 2 Types of Water Snakes in Maryland

There are just 2 water snakes in Maryland, the northern water snake and the plain-bellied water snake (aka red-bellied water snake).

1. Northern Water Snake

Scientific name: Nerodia sipedon

The common water snake, or the northern water snake, is the most populated type of water snake and is very easy to find in Maryland. This snake is a light brown or gray color with red or dark brown cross-bands and splotches along its back or sides. On average, the common water snake grows to between two and three and a half feet in length as adults.

This snake commonly is found basking on logs and rocks. They also commonly inhabit reservoirs in the limestone that lines all of the rivers’ shorelines. It’s clear to see why this snake occurs in all of the state of Maryland, as well as most of New England including Pennsylvania to the north.

They are live-bearers, meaning that instead of laying eggs, they give birth to 10-15 live young in the late summer.

2. Plain-bellied Water Snake

Scientific name: Nerodia erythrogaster

The plain-bellied water snake, or red-bellied water snake, is commonly found in Maryland and the eastern half of the United States. These water snakes averages two and a half feet to four feet long and has a gray or green/grey back without markings. Their belly tends to be reddish orange, hence their name.

This species prefers the quiet waters of swamps, sloughs, lakes, and ponds. They bask on logs in shallow water, on branches above the water, or along the shore. They are not venomous, but will strike or bike if threatened or cornered.

Plain-bellied water snakes feed off of fish, toads, frogs, tadpoles, salamanders, and crayfish. This snake is aquatic, but it may be seen basking on logs in water or along the shoreline. Like most water snakes, it is non-venomous, but they will release large amounts of nasty-smelling musk from glands at the base of the tail.

Like other water snakes, their young are born alive in late summer.
