Common Hound'S-Tongue

<em>Cynoglossum officinale</em>, commonly known as common hound's tongue, is a biennial herb in the family Boraginaceae. It is classified as Least Concern on the IUCN Red List, with populations documented across Europe — including eight European countries — and North America. The species typically inhabits disturbed soils, roadsides, dry grasslands, coastal dunes, and open woodland edges in temperate climates. It is recognized by its deep reddish-purple flowers and rough, tongue-shaped leaves that give the plant its common name. The species contains pyrrolizidine alkaloids and has been used historically in folk medicine, though it is considered toxic to livestock. Diet information for this species is not available in current records. 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。
