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。

Eunotia serraは背側縁に沿って目立つ歯状の波状起伏を持つ湾曲した細胞輪郭で特徴づけられる独特の淡水珪藻です。湿地池、山岳渓流、貧栄養湖を含む酸性の栄養の乏しい淡水環境に生息します。この光合成珪藻は酸性の貧栄養淡水環境の生物指標です。
