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.

Common Water Rat

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Clouded Leopard

最大26kgまで成長する中型の野生ネコであるウンピョウは、ヒマラヤ東部から東南アジアを経てボルネオに至る熱帯・亜熱帯の森林に生息します。独特の雲状の被毛模様から名付けられたこの種は、野生ネコの中で頭骨サイズに対して最も長い犬歯を持ち、木を頭から下に降りることができる優れた登攀者です。森林伐採により危急（VU）種とされていますが、総個体数は十分に把握されていません。

Common Water Rat

<em>Hydromys chrysogaster</em>, commonly known as the common water rat or rakali, is a semi-aquatic rodent in the family Muridae, native to Australia and New Guinea. It is classified as Least Concern by the IUCN, reflecting its relatively stable population across a broad range of freshwater and estuarine habitats on the Australian continent and associated islands. The species typically inhabits the banks of rivers, lakes, wetlands, and estuaries, where it constructs burrows in streambanks. It is highly adapted for an aquatic lifestyle, with partially webbed hind feet, a flattened head, and a dense waterproof coat. <em>Hydromys chrysogaster</em> is a carnivore, typically feeding on fish, crustaceans, mussels, frogs, and aquatic invertebrates, which it often carries to elevated feeding platforms to consume. The species is nocturnal and crepuscular, most active during early morning and evening hours near the water's edge. Biological traits including average lifespan, body length, and weight remain poorly documented in standardized databases, though adults are generally robust for a rodent, reportedly reaching body lengths of 20–35 cm excluding the tail. Geographic range details for this particular record remain incompletely documented in available data sources. Ecologically, the common water rat is an important apex predator in small-scale freshwater food webs and serves as an indicator species for wetland health in Australian riparian systems.
