The European water shrew is a small mammal found in wetland habitats across Europe and parts of Asia. It has a streamlined body, webbed feet, and a long snout, which help it swim and hunt for aquatic prey like insects, fish, and amphibians. This species is known for its high metabolism and can dive underwater for several minutes while searching for food. The European water shrew is primarily nocturnal and is an important part of its ecosystem, helping to control insect populations and serving as prey for larger animals.
