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。

コブハクチョウ

世界で最もよく見られる白鳥であり最大の飛行鳥の一つで、コブハクチョウ（Cygnus olor）は最大 15 kg に達し、ヨーロッパとアジア全域の湖、川、沿岸湾に生息し、北アメリカとオーストラリアにも広く移入個体群があります。名前に反して、コブハクチョウはシューという音、うなり声、翅の風切り音など様々な音を出します。雄は縄張りを激しく防衛し、強力な翅の一撃で人間を傷つけたり犬を溺死させたりする能力があります。
