Common Birdwing

The common birdwing (<em>Troides helena</em>) is a large and striking butterfly of the family Papilionidae, classified as Least Concern on the IUCN Red List. It inhabits terrestrial and freshwater environments across its range in South and Southeast Asia. <em>Troides helena</em> is among the larger birdwing butterflies, with males displaying vivid yellow and black coloration on the hindwings, while females are typically larger and more cryptically marked. The species is often found in tropical and subtropical forest habitats, where it visits flowering plants for nectar. Larvae of birdwing butterflies typically feed on Aristolochia vines, which contain toxic alkaloids that are sequestered by the caterpillars and retained in adult tissues as a chemical defense. Despite its Least Concern status, birdwing butterflies are subject to trade regulations due to their attractiveness to collectors. 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.
