European otter

ヨーロッパカワウソ(Lutra lutra)はヨーロッパとアジア全域の清流、渓流、海岸線に生息するスリムな半水生のイタチ科動物です。体長最大1.3メートルに達し、敏感なヒゲで獲物の動きを感知して魚を狩る非常に優れた能力を持っています。豊富な魚がいる汚染されていない水が必要で、淡水生態系の健全性の指標種として知られています。かつて狩猟と汚染によって西ヨーロッパでほぼ絶滅の危機に瀕していましたが、水質改善に伴い個体数が大幅に回復しました。

jaguar

アメリカ大陸最大のネコ科動物で、体重は最大100kgに達し、がっしりとした筋肉質の体型と特有のロゼット模様の毛皮を持つ。メキシコから南アメリカにかけて分布し、アマゾンやパンタナルが主要生息地となる。優れた水泳能力を持つ頂点捕食者であり、獲物個体数の調節に重要な役割を担う。森林破壊により生息域が縮小し、準絶滅危惧に分類されている。
