Coloma’s Glassfrog

Nymphargus colomai, commonly known as Coloma's Glassfrog, is an amphibian species belonging to the genus Nymphargus within the family Centrolenidae. Glassfrogs are named for their translucent ventral skin, through which internal organs are visible, a trait characteristic of this family. This species is classified as Endangered, indicating a high risk of extinction if current conditions and threats persist within its range. It inhabits freshwater-associated environments, moist forests, and wetland habitats typical of neotropical regions, where glassfrogs are typically found on vegetation near fast-flowing streams. Specific country-level distributional records are not detailed in current documentation. The reproductive biology of glassfrogs involves egg deposition on vegetation overhanging water, with hatching tadpoles dropping into streams below. Dietary information specific to this species has not been documented, though centrolenid frogs generally consume small invertebrates. Biological traits of this species remain poorly documented in the scientific literature. Threats facing Nymphargus colomai include deforestation, stream degradation, and the chytrid fungal disease affecting amphibians globally.

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.
