Collared Sprite

The Collared Sprite, known scientifically as <em>Thainycteris aureocollaris</em>, is a bat belonging to the order Chiroptera. <em>Thainycteris aureocollaris</em> is distinguished by a golden or pale collar of fur around the neck region, which gives rise to the species epithet "aureocollaris" — meaning golden-collared in Latin. The species inhabits diverse terrestrial and aquatic ecosystems. Bats of this type are generally nocturnal, roosting during the day and emerging at night to forage on flying insects using echolocation. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sprite is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is not currently considered to be at significant risk of decline.

Polar bear

지구상에서 가장 큰 육상 육식동물인 북극곰은 700kg을 넘을 수 있으며 캐나다에서 러시아까지 북극 해빙 전역에 분포한다. 고리 물범과 수염 물범을 사냥하기 위해 해빙에 의존하는 고도로 특수화된 해양 포유류이다. 광활한 거리를 헤엄쳐 다닐 수 있는 뛰어난 수영 실력을 가지고 있다. 취약종으로 등재되어 있으며, 기후 변화로 인한 급격한 북극 해빙 감소로 심각한 압력을 받고 있다.
