Common,Banded Bullfrog

The common banded bullfrog (<em>Kaloula pulchra</em>) is a compact amphibian native to the Indomalayan biogeographic region, where it typically inhabits moist broadleaf forests, coniferous forests, and montane environments. Its geographic range spans several Southeast and East Asian countries, including Brunei, the Philippines, Singapore, and Taiwan. The species is classified as Least Concern on the IUCN Red List, reflecting a relatively stable population across its native range. It is often associated with humid forest floors and edge habitats, where moisture levels support its amphibian physiology. The banded bullfrog is recognizable by its stout body and the distinctive pale lateral stripe that runs along each side. It is known to shelter in soil crevices and leaf litter during dry periods, emerging to feed and breed after rainfall. Breeding typically occurs in temporary pools and flooded areas following monsoon rains, with males producing loud calls to attract mates. Biological traits of this species remain poorly documented in the scientific literature.

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.
