Complex-toothed Flying Squirrel

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

<em>Comatricha ellae</em> is a plasmodial slime mold in the class Myxomycetes, order Stemonitidales, belonging to the diverse genus <em>Comatricha</em>. Members of this genus are characterized by their stalked sporangia with a persistent stalk and an elaborate internal capillitial network that aids in spore dispersal. <em>C. ellae</em> has been recorded from Europe and South America, growing on decomposing wood, bark, and other plant debris in moist forest environments. The feeding stage of the organism is a multinucleate plasmodium that migrates across substrates and engulfs microorganisms and organic particles. Upon maturation, the plasmodium aggregates and differentiates into sporangia that release airborne spores. As with other myxomycetes, the species lacks conventional biological traits such as body length or mass, and no quantitative metrics are available. It is not evaluated on the IUCN Red List.

Complex-toothed Flying Squirrel

<em>Trogopterus xanthipes</em>, the complex-toothed flying squirrel, is a medium-sized gliding rodent in the family Pteromyidae endemic to China, where it inhabits montane broadleaf and mixed forests at elevations typically between 1,000 and 2,700 metres in provinces including Sichuan, Yunnan, Guizhou, Hubei, and neighbouring regions. This species is the sole member of the genus Trogopterus and is distinguished by complex tooth morphology compared to other flying squirrels. Like all flying squirrels, it possesses a patagium — a gliding membrane stretching between fore and hind limbs — that enables it to glide between trees rather than undertake powered flight. The complex-toothed flying squirrel is nocturnal and arboreal, spending its days sheltering in tree hollows and foraging at night for leaves, bark, seeds, and fungi. Its faeces, known as Wuflingzhi, have been used in traditional Chinese medicine for centuries, leading to trapping pressure in parts of its range. The IUCN classifies this species as Near Threatened, reflecting population decline driven by overhunting for medicinal use and ongoing habitat loss from logging and agricultural encroachment in montane forests. Biological traits including average body mass, lifespan, litter size, and home range are partially documented but detailed population estimates are limited. Conservation measures include legal protections under Chinese wildlife law.
