gorilla

世界最大の霊長類であるニシゴリラは体重が最大180kgに達し、赤道アフリカの熱帯・亜熱帯の森林に生息する。主に草食性で、群れを守り社会的な対立を仲裁するシルバーバック雄が率いる家族集団を形成する。森林破壊、食肉目的の密猟、エボラウイルス感染症の流行により脅威にさらされており、近絶滅種（CR）に指定されている。

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。
