collared mangabey

The Collared Mangabey, known scientifically as <em>Cercocebus torquatus</em>, is an Old World monkey belonging to the family Cercopithecidae. As a member of the genus Cercocebus, <em>Cercocebus torquatus</em> is recognised by its distinctive appearance, which typically includes a pale or white collar of fur around the neck region that contrasts with darker body colouration, lending the species its common name. Collared Mangabeys are typically associated with tropical rainforest habitats, particularly swamp forests and riverine forest environments, where they forage for fruits, seeds, invertebrates, and other food items on both the ground and in the canopy. The species is known for its loud, distinctive calls, which are used for communication across forest territories. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Mangabey is currently assessed as Endangered on the IUCN Red List, primarily due to ongoing habitat loss from forest clearance and hunting pressure across its range.

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。
