サボテンフィンチ

Geospiza scandens, commonly known as the common cactus finch, is a bird species found in Ecuador and with records from Norway. It typically inhabits aerial, terrestrial, and aquatic environments, often closely associated with arid island ecosystems where cacti are prevalent. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently at risk of significant population decline at a global level. The common cactus finch belongs to the genus Geospiza within the family Thraupidae and is among the iconic Darwin's finches of the Galápagos Islands. It typically feeds on the nectar, pollen, and seeds of cactus plants, particularly Opuntia, and plays an important role as a pollinator and seed disperser within its island habitat. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. Population trends are considered stable, and the species remains an important subject of evolutionary and ecological research.

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。
