Collett’s Tree Frog

Polypedates colletti, commonly known as Collett's Tree Frog, is a species belonging to the genus Polypedates within the family Rhacophoridae, a group of arboreal frogs distributed across South and Southeast Asia. This species inhabits freshwater-associated environments, moist forests, and wetlands, where it typically takes refuge in vegetation near standing or slow-moving water bodies. Tree frogs in this genus are known for constructing foam nests in which eggs are deposited, often above water sources so that hatching tadpoles drop directly into the water below. The species is assessed as Least Concern by major conservation bodies, indicating that current population levels are not considered at elevated risk of decline, though habitat degradation in its range regions may pose future threats. Specific geographic countries of occurrence are not detailed in current records. Dietary information specific to this species has not been documented. Biological traits of this species remain poorly documented in the scientific literature. Further field studies are needed to fully characterize the ecology and distribution of Polypedates colletti.

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。
