Collett’s Tree Frog

<em>Polypedates colletti</em>, commonly known as Collett's Tree Frog, is a species belonging to the genus <em>Polypedates</em> 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 <em>Polypedates colletti</em>.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
