ハナサシミツドリ

The cinnamon-bellied flowerpiercer (Diglossa baritula) is a small, specialized bird in the family Thraupidae, found in montane cloud forests of Mexico and Central America, from the Sierra Madre del Sur in southern Mexico south through Guatemala, El Salvador, Honduras, and Nicaragua. It inhabits humid montane forest, cloud forest, and forest edge vegetation at elevations from approximately 1,000 to 3,000 meters. True to its name, the flowerpiercer uses its specially adapted, hooked bill to pierce the base of tubular flowers and extract nectar without pollinating the plant—a form of nectar theft. The male has gray-black plumage with a cinnamon-rufous belly, while females are brownish. The species is classified as Least Concern by the IUCN, with populations considered stable across its Mesoamerican mountain range. It is a resident of Central American and Mexican highland forests and is entirely absent from Europe; Norwegian database records are data entry errors. The flowerpiercers (Diglossa) represent a fascinating adaptive radiation in the Neotropics, with each species evolving slightly different bill morphologies for exploiting different flower types. Cloud forest habitats in Mesoamerica face ongoing deforestation pressure, but the species' broad elevation range provides some resilience.

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。
