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。
red kangaroo
アカカンガルー(Macropus rufus)は地球最大のカンガルーであり最大の有袋類で、体高2メートル、体重90kgに達し、オーストラリア内陸の乾燥・半乾燥地域に生息する。過酷な砂漠環境に高度に適応しており、植物から水分を抽出することで長期間水なしで生存できる。強力な後ろ足で9メートルのジャンプと時速70kmの走行が可能だ。オスはメスを巡って儀式的なボクシング対決を繰り広げる。
