He lives in the wet high-mountain forests of the caldera in the in the east of Australia, on the border of Queensland and New South Wales [2] . Known for the small number of caught specimens [3] . A descriptive and genetic comparison made it possible to isolate Antechinus arktos into a separate species, previously its samples were attributed to the subspecies Antechinus swainsonii mimetes [2] . Due to the small size and limited habitat, the Baker group recommended that Antechinus arktos be classified as an endangered species. Scientists noted that there is a reduction in its range, probably under the influence of climate change, and that more research is needed to clarify the conservation status of the species [3] .
Informally, researchers call the animal the black-tailed marsupial mouse due to the corresponding color of the tail. The daisy mouse looks different in contrasting colors: the gray-brown head turns into a red-brown knuckle, the paws and tail are evenly painted black, and the red-brown hair on the eyelids forms spots around the eyes and marks on the cheeks. The short, dense fur on the tail differs from the long, shaggy fur on the body [4] .
