Common Glider

Neptis sappho, commonly known as the common glider, is a butterfly in the family Nymphalidae. The species has a broad European distribution, with documented occurrences in 19 countries across the continent. Neptis sappho typically inhabits woodland edges, clearings, and scrubby areas where its larval host plants, primarily species of legumes such as Lathyrus and Vicia, are available. The species is assessed as Least Concern, reflecting its reasonably wide distribution across temperate and sub-Mediterranean Europe. The common glider is named for its characteristic flight pattern, which involves alternating periods of gliding and flapping, producing a distinctive sailing motion through woodland habitats. Its wings are dark brown with white bands and spots that create a striking pattern visible during flight. Biological traits of this species remain poorly documented in the scientific literature. The species typically produces one or two generations per year depending on latitude and climate, and adults are often observed nectaring at flowers in sunny woodland clearings and along forest margins.

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。
