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。

Chaetoceros diversusは、珪藻類の中で最も種が多い属の一つに属する海産浮遊珪藻類だ。水柱内での沈降速度を低下させる長い針状の剛毛（糸状突起）を持つ珪酸質細胞の鎖状群体を形成する。この珪藻は世界中の沿岸および外洋環境に生息し、海洋一次生産と地球炭素循環に重要な役割を果たす。
