One of the most common, yet misunderstood snakes in Indiana is the northern water snake (Nerodia sipedon). This non-venomous species has been quite popular on social media. Unfortunately, it is often mislabeled as the venomous cottonmouth (Agkistrodon piscivorus). Northern or common water snakes are found state-wide in most wetland areas. Creeks, rivers, lakes, ponds, and swamps are typical habitat. They may easily be spotted basking on log jams, rocks, and other structures. This semi-aquatic snake feeds chiefly on fish but will take amphibians. These non-venomous snakes are typically feisty when held and they may bite repeatedly. This common water snake may reach lengths of up to four feet.
Young are light grey with dark bands. Adults are variable from gray, tan, and reddish bands to almost entirely black in appearance. The similar midland water snake (Nerodia s. pleuralis) is found in the southern third of the state. Visually, dark bands on the midland are usually fewer than 30. The dark bands are narrower than the light spaces. Midlands and northerns interbreed and intergrade where the ranges overlap. This is a live baring species and up to 50 young are born in August to September. Please do your best to educate others regarding this harmless, beneficial species!
