African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

brown-throated three-toed sloth

ノドブトウミオサミオは世界で最も動きの遅い哺乳類のひとつで、中南米の熱帯雨林の樹冠に逆さまにぶら下がり、平均時速0.24kmで移動します。低い代謝率は、栄養価の乏しい葉を主食とする適応です。毛皮に生育する藻類がカモフラージュとなり、抗菌性をもつ共生菌を宿すこともあります。蛾、甲虫、菌類がナマケモノの毛皮の中に小さな生態系を形成しています。
