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。

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
