Dasyurids are a family of carnivorous marsupials native to Australia and New Guinea. This group includes well-known species like the Tasmanian devil and various types of quolls. Dasyurids are characterized by their sharp teeth and agile bodies, which help them hunt small animals and insects. These marsupials typically have a nocturnal lifestyle, meaning they are most active at night. Dasyurids vary in size, from the small dunnart to the larger Tasmanian devil. They play an important role in their ecosystems as predators, helping to control populations of other species.
