Common Baskettail

The common baskettail (<em>Epitheca cynosura</em>) is a dragonfly found across terrestrial and freshwater habitats of the United States. It is classified as Least Concern on the IUCN Red List, reflecting a stable and widespread population within its native range. <em>Epitheca cynosura</em> belongs to the family Corduliidae and is typically associated with ponds, lakes, marshes, and slow-moving streams, where its aquatic larvae develop. Adults are often observed patrolling over open water and forest edges in search of prey and mates. The species is named for the basket-like egg mass that females carry at the tip of their abdomen before depositing eggs in water. Males often form feeding swarms, particularly in the morning hours, where they capture small flying insects. Biological traits of this species remain poorly documented in the scientific literature.

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.
