Whether you’re a backyard naturalist or a curious reader, you’ll discover that the Common Shrew is anything but common.
Introducing the Common Shrew
The Common Shrew is one of the most widespread and abundant mammals in Europe. Ranging across the continent from Britain to Siberia, Sorex araneus is a small, insectivorous mammal with a pointed snout, velvety fur, and an insatiable appetite. Though often mistaken for a mouse, the shrew belongs to an entirely different order—Eulipotyphla, which also includes moles and hedgehogs. Adults typically measure between 5 and 8 centimeters in body length, with an additional 3 to 6 centimeters in tail length. Their weight ranges from just 5 to 14 grams, making them one of the lightest terrestrial mammals. Despite this, the Common Shrew’s presence in the ecosystem is substantial due to its high population density and active lifestyle.
