Rana De Ingle Roja

<em>Pristimantis erythropleura</em>, commonly known as the Colombian Robber Frog, is an amphibian species belonging to the genus <em>Pristimantis</em> within the family Craugastoridae, the largest genus of vertebrates by species count globally. This species is assessed as Least Concern by major conservation bodies, indicating stable populations without immediate elevated extinction risk. It has been documented in Colombia, where it inhabits freshwater-associated environments, moist forests, and wetland habitats typical of neotropical Andean and foothill ecosystems. Pristimantis frogs are direct-developing, bypassing a free-living tadpole stage entirely, with fully formed froglets hatching directly from terrestrially deposited eggs. This reproductive strategy confers independence from standing water for reproduction, enabling colonization of a wide range of humid forest microhabitats. Dietary information specific to this species has not been documented, though pristimantid frogs typically consume a variety of small invertebrates. Biological traits of this species remain poorly documented in the scientific literature. Continued forest conservation in Colombia is important for maintaining habitat availability for <em>Pristimantis erythropleura</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.
