Description

Water Shrews are almost invariably found near streams or other bodies of water, where they find food and also escape from predators. These shrews readily dive to stream bottoms, paddling furiously to keep from bobbing to the surface—their fur, full of trapped air, makes them buoyant. They feed on aquatic invertebrates, insect larvae, and even small fish. In the water they are susceptible to predation from larger fish and snakes. On land, Water Shrews have a more typical shrew diet, feeding on a variety of invertebrates, including earthworms, snails, and insects. They also eat fungi and green vegetation.
