Coast Coral Tree

Coast coral tree (Erythrina caffra) is a large, semi-deciduous tree in the family Fabaceae, native to the subtropical coastal forests and riparian zones of the eastern coast of South Africa and coastal Mozambique. It grows in coastal dune forest, riverine forest margins, and rocky hillsides near the sea, often becoming a prominent canopy tree in coastal forest. The trunk is covered in distinctive corky, spiny bark; branches are armed with short thorns; and spectacular clusters of bright red, tubular flowers are produced before or with the new leaves in late winter and spring, providing an important nectar source for sunbirds and other nectarivores. Fruit pods are long, woody, and contain bright red seeds. Coast coral tree is widely planted as a street tree, shade tree, and garden specimen across subtropical coastal cities and is the official tree of Durban, South Africa. It is assessed as Least Concern by the IUCN. Historically, various parts of the tree were used medicinally by Zulu and Xhosa communities. In cultivation it has naturalised in Hawaii and other tropical regions.

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。
