Hohojirozame

地球上で最大の捕食性魚類であるホホジロザメは、全世界の主要な大洋の冷涼な沿岸・外洋域に生息し、体長6メートル、体重2,000キログラムに達することがあります。海洋哺乳類、大型魚類、海鳥を主な獲物として下方からの待ち伏せ攻撃を行う最上位捕食者です。その恐ろしい評判にもかかわらず、人間への非挑発的な攻撃は極めてまれです。フカヒレ採取、混獲、目的的漁獲によって個体数が減少しており、多くの地域で法的保護を受けているにもかかわらず危急（VU）に分類されています。

Buckelwal

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。
