Antechinus is a genus of small marsupial mammals, native to Australia. There are several common synonyms for this word, including the Dunnart, Mouse-marsupial, and Native Mouse. These small creatures have short fur, sharp teeth and are known for their high-rate of reproduction. They are members of the family Dasyuridae and are commonly found in areas ranging from dense forests to grassy fields. Dunnarts are nocturnal creatures, feeding on insects, small mammals, and birds. They are known for their unique behavior of adopting suicidal mating, where males die immediately after the mating season due to rapid hormonal changes. Overall, these small relatives of the Tasmanian Devil have a fascinating role to play in the Australian ecosystem.
