Common iceplant

<em>Mesembryanthemum crystallinum</em>, commonly known as the common iceplant, is a succulent annual or short-lived perennial in the family Aizoaceae. Its conservation status has not been formally evaluated by the IUCN. The species is distributed across Asia, Europe, North America, and South America, with a wide global footprint that includes both native populations and naturalized occurrences. It typically inhabits coastal and arid environments, saline soils, disturbed ground, and rocky slopes where competition from other vegetation is limited. The plant is named for the glistening bladder-like cells on its surface that resemble ice crystals. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.

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。
