Common water snake
The average length of a common water snake is between 25 and 40 inches, and their builds range from medium to heavy. The head is separate from the neck. Pattern in juveniles can very significantly diverge from pattern in adults. Juveniles have dark cross bands on a background that is either light brown, tan, or gray. These cross bands are very distinct, and some may be a color that is either red or orange-brown. As it approaches the tail, the pattern transforms into blotches. Adult patterns become darker as the animal ages, and in old individuals they may appear to be a solid brown or black color. The color of the belly can range from cream to a reddish hue, becoming darker toward the tail and featuring dark semicircles.
The Common watersnake is the most common species of aquatic snake found in Indiana. It may be discovered in virtually every habitat that has water, including ponds, lakes, swamps, streams, and even fish ponds in people's backyards. They are most comfortable in water that is warm, permanent, and shallow, and they like to have access to places where they may sun themselves, such as rocky ledges, logs, and bridge piers. They may be discovered in both urban and rural areas of the world. As winter approaches, it is possible to find them far from bodies of water as they make their way to their slumbering grounds.
