Epaulard

イルカ科で最大の種であるシャチ(Orcinus orca)は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。

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。
