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。

Chaetoceros minimusはChaetocerota科の小型海産浮遊珪藻類で、各細胞の角から伸びる長い剛毛が特徴だ。属内で最も小さい種の一つで、沿岸および外洋水域に広く分布し海洋一次生産に大きく貢献する。他の糸状突起珪藻類と同様に鎖状群体を形成でき、海底への炭素輸出に重要な役割を果たす。
