Shiroagogaeru

<em>Polypedates leucomystax</em>, commonly known as the four-lined tree frog or common tree frog, is a medium-sized arboreal frog in the family Rhacophoridae, widely distributed across South and Southeast Asia. Its range extends from Bangladesh and northeastern India through Myanmar, Thailand, Vietnam, the Philippines, Malaysia, and Indonesia, making it one of the most broadly distributed tree frog species in the region. This species typically inhabits tropical and subtropical moist forests, forest edges, agricultural areas, gardens, and urban environments, demonstrating a high tolerance for human-modified habitats. The dorsal surface is pale brown to cream, typically marked with four dark longitudinal stripes that give the species its common name, though considerable color variation exists. <em>Polypedates leucomystax</em> is predominantly arboreal and nocturnal, descending to breed in temporary pools, rice paddies, and other standing water bodies. It produces foam nests that are attached to vegetation overhanging water, within which eggs develop before tadpoles fall into the water below. The diet consists primarily of insects and other small invertebrates. The species is currently assessed as Least Concern by the IUCN, with a stable and widespread population. Biological traits such as average lifespan, body length, and weight remain poorly documented at the species level 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。
