watersnake

Watersnake refers to a group of nonvenomous snakes belonging to the subfamily Natricinae. These snakes are found in various aquatic and semi-aquatic habitats across North America, Europe, and Asia. Their common name derives from their strong association with water bodies such as lakes, ponds, rivers, and marshes.

Watersnakes are typically characterized by their robust bodies and keeled scales, which give them a somewhat rough texture. Coloration varies widely among species and can include shades of brown, gray, olive, or black, often with patterns of stripes, bands, or blotches that can provide camouflage in their environment. Their diet primarily consists of fish, amphibians like frogs and salamanders, and aquatic invertebrates.

While generally harmless to humans, some watersnakes may bite defensively if handled or threatened. These bites are not venomous and typically cause minor localized pain and swelling. Their role in the ecosystem is important, as they help control populations of their prey animals. Common genera include Nerodia in North America and Natrix in Europe and Asia. Many species are viviparous, meaning they give birth to live young. The term "watersnake" is a common name and does not represent a single taxonomic classification but rather a common ecological niche occupied by several distinct snake genera.
