Habitat & Geographic Range

Clouded Leopard

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types spanning the Australasia and Indomalayan and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across China, Indonesia, Malaysia, Myanmar, and Thailand. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Complex-toothed Flying Squirrel

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Clouded Leopard

A medium-sized wild cat weighing up to 26 kg, clouded leopards inhabit tropical and subtropical forests from the eastern Himalayas through Southeast Asia to Borneo. Named for their distinctive cloud-like coat markings, they possess the longest canine teeth relative to skull size of any wild cat and are exceptional climbers able to descend trees headfirst. Vulnerable due to deforestation, though the total population remains poorly known.

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.
