Buckelwal

大型クジラの中で最も曲芸的なクジラのひとつであるザトウクジラは、繁殖期にオスが歌う複雑で神秘的な歌で知られており、数時間にわたって続き時間をかけて変化していきます。体長16m、体重30トンに達し、哺乳類の中で最長の回遊を行います。全海洋に分布し、協調的なバブルネット採餌でオキアミや小魚を捕食します。歴史的な捕鯨後の個体数はおおむね回復しています。

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。
