Chloronate Huia Frog

The Chloronate Huia Frog (Odorrana chloronota) is a medium-sized ranid frog in the family Ranidae, occurring in the subtropical and tropical forests of southern and southeastern China, Vietnam, Laos, and adjacent Southeast Asia. It belongs to the genus Odorrana, a diverse group of frogs characterised by the presence of odorous skin secretions — the name derives from the distinctive smell produced by their granular dorsal glands, which may serve a defensive function. The chloronate huia frog inhabits fast-flowing rocky streams in hilly and montane forest, where both adults and tadpoles are adapted to strong currents. Tadpoles often possess an oral sucker-like disc enabling them to adhere to smooth rock surfaces in torrent conditions. Adults are typically found perched on rocks or riparian vegetation near streams, and like many stream-dwelling Odorrana, breeding is closely tied to the seasonal pattern of stream flow and rainfall. The species is insectivorous, taking a range of invertebrates encountered near its stream habitat. The IUCN classifies the Chloronate Huia Frog as Least Concern, with a broad range and no indication of rapid population decline. Ongoing threats within its range include deforestation, stream degradation, and emerging infectious diseases such as chytridiomycosis that affect ranid frogs globally.

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.
