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。

Symphytocarpus amaurochaetoidesは森林環境の腐朽木材や植物残渣に暗色の集合胞子嚢を形成する変形菌(粘菌)です。運動性のある栄養原形質と生殖的な胞子嚢段階を交互に繰り返す生物群に属します。他の変形菌と同様に、森林生息地で細菌と腐植質を餌とすることで微生物生態に貢献しています。
