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。

large flying fox

世界最大のコウモリ種で、翼開長は最大1.5メートルに達し、東南アジアからフィリピン・インドネシアにかけての熱帯林に生息する。その名に反して果実と花蜜のみを食べ、熱帯林の樹木にとって不可欠な花粉媒介者・種子散布者となっている。数千頭もの巨大なコロニーでねぐらを作る。食用のための狩猟と生息地破壊により絶滅危惧種に指定されている。
