Lion

アフリカ最大の野生ネコ科動物で最大250kgに達し、サハラ以南のサバンナや草原に生息する唯一の社会性ネコ科動物です。雄は象徴的なたてがみで識別されます。頂点捕食者として草食動物の個体群を調節し、生態系のバランスを維持します。生息地の喪失と人間との軋轢により危急種に分類されています。

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。
