Habitat & Geographic Range

백상아리

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate grasslands and steppes, among 9 distinct biome types spanning the Indomalayan and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Chile, Norway, Portugal, and Taiwan. 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.

백상아리

지구상에서 가장 큰 포식성 어류인 백상아리는 전 세계 주요 대양의 시원한 연안 및 원해에 서식하며, 체장 6미터, 체중 2,000킬로그램까지 성장할 수 있습니다. 해양 포유류, 대형 어류, 바닷새를 주요 먹이로 하여 아래에서 기습 공격하는 최상위 포식자입니다. 무서운 명성에도 불구하고 인간에 대한 비도발적 공격은 극히 드뭅니다. 지느러미 채취, 혼획, 목적성 포획으로 개체수가 감소하고 있어 IUCN에서 취약(VU)으로 분류되며, 많은 지역에서 법적 보호를 받고 있습니다.

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.
