Common Ring-Tailed Possum

Fascinating facts about the Common Ring-Tailed Possum

• The common ringtail possum expels specialised faeces called caecotropes while it rests in its daytime nest and then eats them again. This behaviour, known as caecotrophy, is unlike that of koalas and greater gliders, which do not re-ingest their caecal contents. By passing the material back into the stomach the possum extracts additional protein from the otherwise low-nutrient leaves it eats, giving it a nutritional edge in its arboreal diet.
• Nearly all nitrogen that would be lost in waste is reclaimed by the ringtail possum; it recycles 96% of its liver's urea and sends it to the caecum where bacteria convert it into protein. The animal then consumes these nitrogen-rich caecotropes, supplying most of its daily maintenance nitrogen requirement of 290 mg N kg⁻⁰·⁷⁵. Without this re-ingestion it would need to obtain roughly 620 mg N kg⁻⁰·⁷⁵ from its diet, a far greater demand.
• When ambient temperatures rise, the common ringtail possum can deliberately raise its internal temperature, a process called facultative hyperthermia, increasing its body heat from about 29 °C up to 39 °C. This temporary rise reduces the need for evaporative cooling, helping the animal conserve water, which is crucial because roughly 55% of its water comes directly from the leaves it eats.
• Common ringtail possums are highly social and build communal nests, known as dreys, from branches and tree hollows. These groups are fiercely territorial, driving away any unfamiliar conspecifics that approach their nest. A single group may maintain several dreys across its range, showing a strong attachment to each site.
• About 55% of the water ringtail possums obtain comes directly from the leaves and foliage they eat. They must keep their metabolism low and stable to avoid dehydration.

About the Common Ring-Tailed Possum

In the moonlit eucalyptus forests, a fleck of silver darts through the underbrush, the Common Ring-Tailed Possum weaving a silent path with an air of quiet purpose. With prehensile tail aloft, a fifth limb guiding its nocturnal wanderings, this diminutive marsupial navigates the shadows with an uncanny agility, its large, round eyes drinking in the faint light. As it pauses to survey its surroundings, the possum's gentle, pointed face seems almost otherworldly, a fleeting glimpse into a secret realm that thrives beneath the cover of darkness.
