Anabaena birgeiはNostocaceae科に属する淡水性シアノバクテリアで、大気中の窒素を固定する異型細胞が栄養細胞の連鎖の間に散在しています。湖や池で浮遊生物として生活し、貧栄養から中栄養の淡水系への窒素供給に貢献します。湖沼学者エドワード・バージ（Edward Asahel Birge）にちなんで命名され、北半球の温帯湖で見られます。

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。
