common bottlenose dolphin

最も研究され、最も知られているイルカ種であるバンドウイルカは、沿岸の浅瀬から外洋まで世界中の温暖な海域と温帯海域に生息します。体に対して大きな脳を持つ高度に知性的なこの種は、自己認識、複雑なコミュニケーション、社会的学習を示します。流動的な分裂融合社会で生活し、魚を追い込むために協力します。海洋生態系の健全性の重要な指標種です。

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。
