モグリウミツバメ

<em>Pelecanoides urinatrix</em>, the common diving petrel, is a seabird in the family Procellariidae distributed across the Southern Ocean and subantarctic regions, with records extending to Norway. This species typically inhabits open marine environments and coastal cliffs, where it nests in burrows on islands and steep shorelines. The common diving petrel is notable for its highly specialized diving behavior, using its wings to propel itself underwater in pursuit of small fish, crustaceans, and zooplankton. Its compact body, short wings, and strong feet make it well adapted to both aerial and aquatic locomotion, though flight is typically low and whirring. <em>Pelecanoides urinatrix</em> is generally nocturnal at its nesting colonies, helping to reduce predation risk. Adults typically form long-term pair bonds and raise a single chick per breeding season in underground burrows. The species is assessed as Least Concern, though some island populations have experienced pressure from introduced predators. Its ecology reflects a highly marine-adapted lifestyle across cold southern waters.

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。
