Colombian Swamp Frog

Pseudopaludicola pusilla, the Colombian swamp frog, is a small anuran amphibian in the family Leptodactylidae, distributed across Colombia and Venezuela. This species inhabits freshwater ecosystems including marshes, flooded grasslands, seasonally inundated forests, and the margins of streams and ponds within moist forest biomes. Frogs of the genus Pseudopaludicola are characteristically tiny and highly active, often difficult to observe directly despite their occasionally conspicuous advertisement calls during the breeding season. Pseudopaludicola pusilla is assessed as Least Concern by the IUCN, indicating that its populations are not currently considered at significant risk of decline across its range. As a small insectivore, this species feeds primarily on ants, mites, and other minute invertebrates, and serves as prey for a range of predatory vertebrates inhabiting its wetland and forest edge habitats. Seasonal flooding patterns strongly influence its reproductive activity and habitat availability. Biological traits of this species remain poorly documented in the scientific literature.

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。
