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。

最も個体数の多い野生の馬科動物であるサバンナシマウマ（Equus quagga）は、東アフリカと南アフリカの草原およびサバンナに小さな家族グループから大規模な集団まで様々な形で生息する。個体ごとに独特の白黒の縞模様は、捕食者を混乱させ、吸血昆虫を防ぎ、個体識別を助けると考えられている。シマウマはライオン、ハイエナ、ワニの主要な餌となり、サバンナの食物網を支える。
