Northern watersnake (sub-adult)

Description:

The Northern water snake is a large, nonvenomous, well-known snake in the Colubridae family that is native to North America. They are active during the day and at night. They are most often seen basking on rocks, stumps, or brush. During the day, they hunt among plants at the water's edge, looking for small fish, frogs, worms, leeches, crayfish, salamanders, small birds and mammals. At night, they concentrate on minnows and other small fish sleeping in shallow water. The Northern water snake can grow up to 4.4' long. They can be brown, gray, reddish, or brownish-black. They have dark crossbands on their necks and dark stripes and blotches on the rest of their bodies, often leading to misidentification as cottonmouths or copperheads by novices. They darken as they age. Some will become almost completely black. The belly of this snake also varies in color. It can be white, yellow, or gray. Usually it also has reddish or black crescents. Northern water snakes mate from April through June. They are ovoviviparous (live-bearers), which means they do not lay eggs like many other snakes. Instead, the mother carries the eggs inside her body and gives birth to free living young, each one 7.5–9.1" long. A female may have as many as thirty young at a time. They are born between August and October. Mothers do not care for their young; as soon as they are born, they are on their own. Northern water snakes have many predators, including birds, raccoons, opossums, foxes, snapping turtles, and other snakes. They defend themselves vigorously when they are threatened. If they are picked up by an animal, or person, they will bite repeatedly, as well as release excrement and musk. Their saliva contains a mild anticoagulant, which can cause the bite to bleed more but poses little risk to humans. Northern water snakes often share winter dens with copperheads and black rat snakes. They live near lakes, ponds, marshes, rivers, and canals; just about anywhere there is freshwater.
