giraffe

地球上で最も背の高い動物であるキリン(Giraffa camelopardalis)は体高が5.5mに達し、体重は最大1,750kgにもなる。すべての哺乳類と同じ7個の頸椎からなる長い首は、アフリカのサバンナや疎林のアカシアの木に食物を求めて進化した。永続的な絆を持たない緩やかな群れで生活する社会的動物で、超低周波音と身振りで意思疎通する。生息地の喪失と密猟により個体数が減少している危急種である。

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。
