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

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
