ラケットカワセミ

<em>Tanysiptera galatea</em> is a strikingly colored kingfisher in the family Alcedinidae, native to the Maluku Islands and New Guinea in the Australasian region. The species is characterized by elongated central tail feathers, a vivid blue and white plumage, and a distinctive red bill. It inhabits lowland tropical forests, forest edges, and secondary growth, where it forages for invertebrates, small lizards, and earthworms typically caught by diving to the ground from low perches. The species nests in arboreal termite mounds, excavating tunnel nests that provide insulation and protection. Its occurrence record in Norway is a clear database artifact; the true range is confined to the islands of eastern Indonesia and New Guinea. The IUCN classifies this species as Least Concern owing to its broad distribution and large populations across suitable forest habitats. Biological traits including average lifespan, body length, and body weight are not consistently recorded across populations in standardized databases, and detailed dietary data remain poorly documented. Conservation concerns center on the continued integrity of lowland forests within its range, particularly in areas facing agricultural conversion and logging pressure.

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。
