<em>Comatricha laxa</em> is a plasmodial slime mold in the class Myxomycetes, order Stemonitidales, with a documented distribution spanning Asia, Europe, and South America. As a member of the genus <em>Comatricha</em>, it forms stalked sporangia with a characteristic capillitium that forms a loose, open network aiding spore dispersal. The species inhabits rotting logs, dead bark, and moist leaf litter in forested environments where conditions support the plasmodial feeding stage. The plasmodium is a multinucleate, macroscopic structure that migrates over substrates to engulf bacteria and other microorganisms. Geographic range data confirm a wide cosmopolitan distribution in suitable habitats across three continents. <em>C. laxa</em> contributes to decomposition and nutrient cycling in woodland ecosystems. No quantitative biological metrics such as body size or mass are applicable to this organism, and it has not been evaluated by the IUCN.

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.
