Cocha Chirping Frog

The cocha chirping frog (Adenomera andreae) is a small terrestrial frog belonging to the family Leptodactylidae, widely distributed across lowland and submontane forest of northern South America, including Venezuela, Trinidad, Guyana, Suriname, French Guiana, and parts of Brazil and Colombia. It inhabits leaf litter, stream margins, and forest floor habitats in humid tropical and gallery forests, where its cryptic brown coloration provides effective camouflage against predators. Like other members of the genus Adenomera, this species practices direct development: eggs are deposited in foam nests on moist land rather than in open water, and juveniles hatch as fully formed froglets, bypassing the free-living tadpole stage entirely. Males produce a distinctive chirping advertisement call, often from concealed positions among roots or leaf debris, to attract females during breeding seasons that may extend throughout much of the year in equatorial localities. The cocha chirping frog is classified as Least Concern by the IUCN, reflecting its broad distribution, presumed large populations, and tolerance for moderately disturbed habitats including secondary forest and forest edges. It can persist in areas subject to low-intensity logging and is frequently encountered in wildlife surveys across its range. Primary threats are large-scale deforestation and drainage of wetland habitats, though these pressures have not yet driven significant population decline across its wide geographic range.

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.
