What is a "water snake"?

A water snake is a non-venomous snake that is highly adapted to aquatic environments. They are commonly found near bodies of water such as lakes, rivers, and wetlands. Water snakes have streamlined bodies and are excellent swimmers, using their flattened tails to propel themselves through the water. They primarily feed on fish and amphibians, and their diet may also include small mammals and birds. While some species of water snakes are docile and relatively harmless to humans, others may become defensive and bite if threatened. Overall, water snakes play a crucial role in maintaining the balance of aquatic ecosystems.
