Atlantic Bluefin Tuna

大西洋クロマグロ（Thunnus thynnus）は大西洋・地中海に生息する世界最大のマグロ類の一種で、体長3メートル・体重700キログラム以上に達する個体が知られる。IUCNレッドリストでは絶滅危惧（EN）に分類されており、寿司・刺身用として極めて高い市場価値を持ち、1尾が3億円以上で取引された事例もある。体温調節能力と高速遊泳能力（時速70キロ以上）を持つ、硬骨魚類の中でも異例の生理的能力を備えた種である。

Cheetah

地球上で最も速い陸上動物で、アフリカとイランの草原において短距離走で時速112kmに達する。深い胸部、長い脚、独特の黒い涙縞模様を持つ細身の体型が特徴だ。他の大型ネコ科動物とは異なり、チーターはチャープ音やパー音で鳴く。生息地の分断と大型捕食者との競争により、残存個体数は約7,000頭のみとなっており、危急種に分類されている。
