大型クジラの中で最も曲芸的なクジラのひとつであるザトウクジラは、繁殖期にオスが歌う複雑で神秘的な歌で知られており、数時間にわたって続き時間をかけて変化していきます。体長16m、体重30トンに達し、哺乳類の中で最長の回遊を行います。全海洋に分布し、協調的なバブルネット採餌でオキアミや小魚を捕食します。歴史的な捕鯨後の個体数はおおむね回復しています。

Eggerelloides mediusは堆積物粒子から多室の凝集した殻を構築する単細胞海洋生物である底生有孔虫です。浅海から中程度の水深の沿岸環境の細粒海洋堆積物に生息します。他の有孔虫と同様に腐植物や細菌を食べ、有機物の再鉱物化を含む底生生地球化学サイクルに役割を果たします。
