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。

Nitzschia intermediaは、Bacillariaceae科に属する羽状珪藻類で、淡水からやや汽水性の生息地に分布し、底生および浮遊生物のニッチを占める。竜骨縫合部と細かい横中心条線を持つ細長い殻は、大型属Nitzschiaの典型的な特徴である。水生モニタリングプログラムにおける中程度の有機物および栄養塩富化の生物指標として機能する。
