Jinbeizame
ジンベエザメ(Rhincodon typus)は世界最大の魚類で、体長12メートル、体重20トンを超えることがあり、世界の熱帯・温暖な温帯海洋に生息します。その巨大な体にもかかわらず、プランクトン、魚卵、小魚を口を大きく開けて泳ぎながら濾過摂食する無害な種です。プランクトンの大発生を追って大規模な季節的回遊を行います。乱獲、船の衝突、フカヒレ取引により、過去75年間で個体数が約50%減少し、絶滅危惧種に指定されています。
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。
