 Also extinct on the mainland, the Tasmanian pademelon ("Thylogale billardierii") is still common in Freycinet National Park but they are rarely seen during the day, coming out at night to feed.Echidnas ("Tachyglossus aculeatus") can be seen during the day foraging through litter on forest floors, or among coastal vegetation, searching for ants or other food sources.The eastern pygmy possum ("Cercartetus nanus") and the little pygmy possum ("Cercartetus lepidus") are listed as vulnerable in several mainland Australian states but are not listed in Tasmania, and although they can be found at Freycinet, sightings of them are uncommon.
