ミナミカマハシ

<em>Rhinopomastus cyanomelas</em>, the common scimitarbill, is a bird in the family Phoeniculidae, order Bucerotiformes, widely distributed across sub-Saharan Africa. It inhabits dry woodland, savanna, and bushveld, typically favoring areas with tall trees that provide nest cavities. Despite limited geographic data in some databases, this species is well-documented across a broad African range from East Africa southward through southern Africa. The common scimitarbill is named for its long, sharply curved bill, which it uses to probe bark crevices for insects, larvae, and spiders. It typically forages alone or in pairs and is known for its loud, repeated whistling calls. <em>Rhinopomastus cyanomelas</em> is classified as Least Concern by the IUCN, with populations considered stable across its extensive range. The species is generally not considered threatened, though localized habitat loss could affect populations in some areas. Biological traits for this species remain poorly documented in the scientific literature, with limited published data on average lifespan, precise body measurements, weight, and detailed dietary composition beyond its general insectivorous behavior.

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。
