Thank you for your question. The snake in your photograph is an eastern wormsnake, scientific name Carphophis amoenus. Wormsnakes are non-venomous. Typical length of adults is 8 - 9 inches. Babies are 3 - 4 inches. They look like adults only somewhat darker. They are characterized by a white or pink belly, the coloring of which extends part way up the sides of the snake. They also have a sharp point or spine at the tip of their tail. 

The eastern wormsnake is found in portions of all the eastern states south of Wisconsin, Michigan, New Hampshire and Vermont, except for Florida. They are generally found in cool, moist hardwood forests. They are active from early spring to late fall. They spend most of their time underground or under logs and stones. If found above ground, it's usually at night during the warmest time of the year.

They feed almost exclusively on earthworms, but may rarely feed on soft-bodied insect larvae and slugs. 

If you pick one up it will wriggle similar to an earthworm. It will also press the sharp point/spine on its tail against your skin, but they don't have enough force to break the skin. Like many other species of snake, they also release a strong-smelling fluid from their anal glands to further discourage you. They almost never bite humans.
