Common Hippopotamus, Hippopotamus, Large Hippo

아프리카에서 가장 위험한 대형 포유류인 하마(Hippopotamus amphibius)는 최대 3,200kg에 달하며 사하라 이남 아프리카의 강, 호수, 습지에 서식한다. 반수생 생활을 하며 하루 16시간까지 물에 잠겨 체온을 조절하고 밤에는 육지에서 풀을 뜯는다. 온순해 보이지만 매우 공격적이고 영역 방어가 강해 매년 수백 명의 인명 피해를 일으킨다. 취약 종으로 서식지 손실과 상아를 노린 밀렵으로 위협받고 있다.

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.
