The Mustelidae family, commonly known as weasels, includes a variety of small to medium-sized carnivorous mammals. This family encompasses animals such as otters, badgers, ferrets, and minks. Mustelids are characterized by their elongated bodies, short legs, and thick fur, which helps them adapt to various environments, from forests to wetlands. Mustelids are known for their agility and hunting skills, often preying on small mammals, birds, and fish. They have a keen sense of smell and are generally solitary animals, although some species, like European badgers, may live in social groups. Their diverse habitats and behaviors make them an important part of many ecosystems.
