Collett’s Tree Frog

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

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>.
