Short-eared possum

The short-eared possum is a species of marsupial in the family Phalangeridae, endemic to Australia. Found north of Sydney, New South Wales, on Australia's eastern coast, the species was once classed under the mountain brushtail possum, its closest relative.
In the wild, they can live for up to 17 years, maintain a stable territory, and invest significant energy and time rearing their young.
Short-eared possums are most commonly found along the southeastern coast of the Australian continent, where they reside in wet rainforests and humid, dense thickets.
