Common Hound'S-Tongue

<em>Cynoglossum officinale</em>, commonly known as common hound's tongue, is a biennial herb in the family Boraginaceae. It is classified as Least Concern on the IUCN Red List, with populations documented across Europe — including eight European countries — and North America. The species typically inhabits disturbed soils, roadsides, dry grasslands, coastal dunes, and open woodland edges in temperate climates. It is recognized by its deep reddish-purple flowers and rough, tongue-shaped leaves that give the plant its common name. The species contains pyrrolizidine alkaloids and has been used historically in folk medicine, though it is considered toxic to livestock. Diet information for this species is not available in current records. 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。
