Overview

The Eurasian water shrew, known in the United Kingdom as the water shrew, is a relatively large shrew, up to 10 cm (4 in) long, with a tail up to three-quarters as long again. It has short, dark fur, often with a few white tufts, a white belly, and a few stiff hairs around the feet and tail. It lives close to fresh water, hunting aquatic prey in the water and nearby.

The Eurasian Water Shrew faces significant population declines primarily due to habitat degradation and loss of clean freshwater environments. Water pollution, agricultural runoff, and wetland drainage have severely impacted the quality of riparian habitats essential for this semi-aquatic species.
