Colombian Four-eyed Frog

<em>Pleurodema brachyops</em>, commonly known as the Colombian Four-eyed Frog, is an amphibian species belonging to the genus <em>Pleurodema</em> within the family Leptodactylidae. The common name refers to the conspicuous glandular swellings on the posterior of the body that resemble eyes, a defensive adaptation thought to deter predators by mimicking a larger, more threatening animal. This species is assessed as Least Concern by major conservation bodies, indicating that its populations are not currently at elevated risk. It has been documented in Colombia and Venezuela, where it inhabits freshwater-associated environments, moist forests, and wetland habitats. Frogs of this genus are typically terrestrial, breeding in temporary pools and humid environments during the wet season. Dietary information specific to this species has not been documented, though small leptodactylid frogs generally prey on invertebrates. Biological traits of this species remain poorly documented in the scientific literature. The species' striking antipredator morphology makes it a subject of interest in herpetological research on defensive behaviors in amphibians.

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.
