The Eurasian water shrew is a small mammal found in wetlands, rivers, and streams across Europe and parts of Asia. It has a streamlined body, webbed feet, and a long snout, which help it swim efficiently and hunt for aquatic insects, small fish, and crustaceans. This shrew is known for its high metabolism and can dive underwater for several minutes while searching for food. Its fur is dense and water-repellent, allowing it to stay warm and dry in cold environments. The Eurasian water shrew is an important part of its ecosystem, helping to control insect populations.
