Common Coral Tree

<em>Erythrina lysistemon</em>, commonly known as the common coral tree or lucky bean tree, is a medium to large deciduous tree in the family Fabaceae. Native to southern Africa, it is particularly characteristic of South Africa's woodlands, bushveld, and coastal forests, and has also been recorded in Portugal as an introduced species. The common coral tree is renowned for its spectacular scarlet tubular flowers, which appear before the leaves in late winter and spring and attract nectar-feeding birds, particularly sunbirds. Its seeds are bright red with a black spot and have been used in traditional jewelry and decoration. The tree produces compound leaves with three broadly ovate leaflets and is armed with sharp curved spines on its trunk and branches. It is assessed as Least Concern by the IUCN. Biological traits of this species remain poorly documented in the scientific literature.

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。
