Brief Summary

Read full entry


Large for a shrew and with velvety dark fur, the Marsh Shrew can be found in marsh, stream, and beach habitats of the coastal rain forest in extreme southwestern Canada and the Pacific Northwest of the United States. This shrew is distinguished from the equally-large water shrew by the absence of a fringe of stiff hairs on its hind toes. The Marsh Shrew has been observed running on the surface of the water for three seconds or so before diving, on its hunt for aquatic insect larvae. With the highest energy, it also consumes earthworms, slugs, snails, termites, spiders, and sowbugs. After a bout of feeding, it will sleep, sometimes for half an hour.
