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.

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
