common bottlenose dolphin

最も研究され、最も知られているイルカ種であるバンドウイルカは、沿岸の浅瀬から外洋まで世界中の温暖な海域と温帯海域に生息します。体に対して大きな脳を持つ高度に知性的なこの種は、自己認識、複雑なコミュニケーション、社会的学習を示します。流動的な分裂融合社会で生活し、魚を追い込むために協力します。海洋生態系の健全性の重要な指標種です。

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。
