モモアカヒメハヤブサ

<em>Microhierax caerulescens</em>, the Collared Falconet, is one of the world's smallest raptors, belonging to the family Falconidae. This species is assessed as Least Concern on the IUCN Red List. It is native to South and Southeast Asia, with its range extending from the Indian subcontinent through Myanmar, Thailand, Laos, Vietnam, and southern China, where it inhabits forest edges, open woodlands, and clearings. Despite its diminutive size, the Collared Falconet is an active predator, hunting insects, small lizards, and occasionally small birds in flight. The genus <em>Microhierax</em> comprises the falconets, all of which are restricted to Asia. The Collared Falconet is named for the prominent rufous or white collar visible on its plumage. Diet, population estimates, and biological measurements such as average length, weight, and lifespan are not specified in the available records. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects a stable population across its broad South and Southeast Asian range.

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。
