The European Weasel (Mustela nivalis) is a small carnivorous mammal found across Europe, parts of Asia, and North Africa. It has a slender body, short legs, and a long tail, typically measuring about 20 to 30 centimeters in length. Its fur is usually brown on the back and white or cream on the belly, providing effective camouflage in its natural habitat. This species primarily inhabits forests, grasslands, and agricultural areas, where it hunts small rodents, birds, and insects. The European Weasel is known for its agility and speed, making it an efficient predator. It plays a vital role in controlling pest populations in its ecosystem.
