Club-tailed Charaxes

Charaxes zoolina, the club-tailed charaxes or club-tailed butterfly, is a medium-sized nymphalid butterfly in the family Nymphalidae, subfamily Charaxinae, native to sub-Saharan Africa. The genus Charaxes is one of the most speciose butterfly genera in Africa, known for robust, fast-flying adults with strongly scalloped hindwings. C. zoolina is distributed widely across sub-Saharan African woodland and forest-margin habitats, from West Africa through East Africa to southern Africa. Adults are typically orange-brown with black borders and pale submarginal spots, similar in pattern to many other Charaxes species. Like other charaxines, adults are attracted to fermenting fruit, sap flows, dung, and carrion rather than flowers, obtaining essential amino acids and minerals from these substrates. Males are territorial, perching on prominent vantage points to intercept females and rival males. Larvae feed on plants in the family Fabaceae, particularly Albizia species. The species is classified as Least Concern by the IUCN given its wide distribution and apparent stability across suitable woodland savanna habitats in tropical Africa.

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。
