Common Field Grasshopper

The Common Field Grasshopper (<em>Chorthippus brunneus</em>) is an orthopteran insect belonging to the genus Chorthippus within the family Acrididae. It is one of the most frequently encountered grasshoppers in northern and western Europe, typically inhabiting dry, open areas such as grasslands, heathlands, roadsides, and disturbed ground. The species is often found in virtually all terrestrial and freshwater habitats across its range. Geographically, <em>Chorthippus brunneus</em> is distributed across Belgium, Denmark, Luxembourg, Norway, and Sweden, among other European countries. The species is assessed as Least Concern on the IUCN Red List. Adults are typically brown to grey in colouration with variable patterning, and males often produce a distinctive short, chirping song used in courtship. As a herbivore, this grasshopper typically feeds on grasses and other low-growing vegetation. Biological traits including average lifespan and body dimensions remain poorly documented in the scientific literature, though adults in temperate regions typically appear from mid-summer through autumn.

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。
