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。

Nodularia litorea は、汽水から海水条件まで幅広い塩分に耐え、沿岸および河口環境に生息する糸状の窒素固定シアノバクテリアである。栄養細胞と異形細胞が交互に並ぶ短いトリコームを形成する。他のNodularia種と同様に、ブルーム形成条件下で肝毒素(ノドゥラリン)を産生する可能性があり、水生生物と水質に危険をもたらす。
