Habitat
Eurasian water shrews primarily inhabit freshwater environments in Europe and parts of Asia, such as streams, rivers, ponds, and marshes with dense vegetation. They prefer areas with soft banks for burrowing and ample cover, avoiding open or dry terrains. These habitats provide both foraging opportunities and protection from predators.
Diet
This species feeds mainly on aquatic and terrestrial invertebrates, including insects, crustaceans, worms, and small fish or amphibians. They hunt actively using their sensitive whiskers and paws to detect prey in water or on land, typically during dawn, dusk, or at night. Feeding behavior involves quick dives and surface foraging to capture live food.
Behavior
Eurasian water shrews are solitary and territorial, defending small home ranges with scent markings and aggressive displays. They are primarily nocturnal, spending much of their time swimming, diving, and foraging near water, while resting in burrows during the day. These shrews exhibit high energy levels and can be vocal, producing high-pitched sounds to communicate or warn off intruders.
Conservation Status
The IUCN classifies the Eurasian water shrew as Least Concern, with a stable population trend across its range. Major threats include habitat loss from urbanization, pollution of waterways, and climate change impacts on freshwater ecosystems.
