Long-tailed pygmy possum
species of mammal
The long-tailed pygmy possum (Cercartetus caudatus) is a diprotodont marsupial found in the rainforests of northern Australia and New Guinea. Living at altitudes of above 1,500 m (4,900 ft), it eats insects and nectar, and may eat pollen in place of insects in the wild.
It is known as sumsum in the Kalam language of Papua New Guinea.
Description
The long-tailed pygmy possum has large eyes, mouse/rodent-like ears, a pouch that opens anteriorly, and a tail that is about one and a half times as long as the body, giving the possum its name.
Behaviour
Not much is known of this possum's behaviour, but what is known is that this species is both nocturnal and arboreal. In cold weather, it becomes torpid and looks and feels dead, but wakes at night. Not much is known on the origin of this torpor.
Life cycle
This species breeds twice a year. Females have one to four young born around January and February and sometimes a second litter from late August to early September. The young leave the nest when they are 45 days old.
This brief starts where responsible research should: with the source description of “Long-tailed pygmy possum” as species of mammal. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of mammal. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Oct 3, 2025. The linked authority identifier is Q209747. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
