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.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
