Bamboo bear

ジャイアントパンダ(Ailuropoda melanoleuca)は中国中部の山岳竹林に生息し、体重最大125キログラムになるクマ科の動物で、食肉目に分類されながら食事の99%を竹が占める特異な食性を持つ。偽の親指(橈側種子骨)を使って竹の茎を把握し、1日14時間もの採食時間を費やす。2016年にIUCNレッドリストで絶滅危惧から危急(VU)へ改善されており、保護繁殖プログラムと自然保護区の設置が個体数回復に貢献している。

Stephanoeca kentiiはロリカを持つ襟鞭毛虫類で、細胞周囲にケイ酸塩片からなる精巧なかご状の構造物(ロリカ)を形成する海洋性単細胞生物です。ピコプランクトン細菌を餌とする沿岸・外洋域の海水に生息します。この種のような襟鞭毛虫類は、動物に最も近縁な現生単細胞生物として科学的関心を集めています。
