地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

Vibrio choleraeはコンマ形で高い運動性を持つグラム陰性の水生細菌で、ヒトにおける汎世界的コレラの病原体です。沿岸河口域、河川デルタ、暖かい海洋環境に生息し、プランクトン特にカイアシ類と関連することが多いです。汚染された水や食品を通じて拡散し、重篤な水様性下痢を引き起こして公衆衛生に大きな影響を与えます。
