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.
