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。

Hira-shumokuzame

最大のシュモクザメ種であるオオシュモクザメは最大6メートルに達し、世界中の熱帯および亜熱帯の沿岸海域に生息します。T字型の特徴的な頭部（セファロフォイル）は電気受容のための感覚表面積を著しく増大させ、砂の中に潜むアカエイを卓越した精度で探知することを可能にしています。アカエイは好物の餌です。高価値のヒレと混獲死亡により個体群が劇的に減少し、絶滅危惧IA類に分類されています。
