Sorex araneus, commonly referred to as the common shrew or the Eurasian shrew, is a small, insectivorous mammal found across Europe and parts of Asia. It is known for its voracious appetite, consuming nearly its own body weight in insects and other prey each day. There are several synonyms for Sorex araneus, including the Nordic shrew, the Northern shrew, and the Eurasian long-tailed shrew. Despite its small size, the common shrew is an important part of many ecosystems, playing a role in controlling insect populations and as a prey item for larger carnivores such as owls and foxes.
