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。

Volvariella volvaceaは「ワラ茸」とも呼ばれ、熱帯アジアで数千年にわたって栽培されてきた独特の托、灰褐色の傘、ピンク色のひだを持つ中型キノコです。東南アジアおよび東アジアの熱帯・亜熱帯地域で、稲藁、堆肥、腐植植物残渣上に生育します。この腐生菌は特に稲藁などの農業残渣を分解し、食用キノコとして広く栽培されています。
