common pelican’s foot

<em>Aporrhais pespelecani</em>, commonly known as the common pelican's foot, is a marine gastropod mollusk belonging to the family Aporrhaidae. This distinctive snail is named for its unusual shell shape, which features a flared outer lip with finger-like projections resembling a pelican's webbed foot. It inhabits sandy and muddy substrates of shallow coastal seas, typically found at depths ranging from the intertidal zone to several hundred metres. The species is distributed across temperate European waters, with confirmed records from Belgium, Denmark, Norway, and Sweden, as well as Turkey, indicating a range spanning the northeastern Atlantic and parts of the Mediterranean and Black Sea. <em>Aporrhais pespelecani</em> typically buries itself partially in soft sediments, where it feeds on organic detritus and microalgae. The species is assessed as Least Concern on the IUCN Red List, reflecting its relatively wide distribution and absence of major threats. Biological traits such as average lifespan, body size, and detailed dietary composition remain poorly documented in the scientific literature. Populations are generally considered stable, though localised habitat degradation from coastal development and trawling may pose risks in certain parts of 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。
