The stone marten, also commonly known as the beech marten, is a small carnivorous mammal found in parts of Europe and Asia. It is known for its sleek body and distinctive facial markings, which include a white patch beneath its eyes. There are several synonyms for the stone marten, including the European pine marten, the forest marten, and the sweet marten. In some regions, it is also referred to simply as the marten or the common marten. Despite its small size, the stone marten plays an important role in its ecosystem as a predator of small rodents and insects. Unfortunately, their populations are threatened by habitat loss and hunting, and conservation efforts are necessary to ensure their survival.
