Asiatic elephant

アジアゾウ（Elephas maximus）はアフリカゾウに比べて小型で、インドから東南アジア・インドネシアに至る森林・草原に生息する。アフリカゾウより小さな耳・丸みのある背・鼻先の1本の指状突起などの形態的特徴を持ち、アジアの文化・宗教と深く結びついており、古来より使役動物・神事に用いられてきた。IUCNレッドリストでは絶滅危惧（EN）に分類されており、野生の個体数は5万頭を下回る。

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。
