イルカの脂肪は、スポーツ万能の秘訣

世界中のいろいろな海に生息しているハンドウイルカ。海水の温度が変わっても、体温を一定に保つことができる。イルカの体の２０％を占めている脂肪が、体温を調節している。脂肪のおかげでイルカは、海が寒くなっても、体温が下がることもない。人間では余分なものというイメージの脂肪だが、イルカにとっては寒い海で泳ぐために必要なものなのである。イルカは生まれたときから、脂肪の割合が多いため、すぐに泳ぐことができる。それだけではない。脂肪はイルカの頭や、耳、背びれと尾びれの間など体の色々な場所についている。これらの脂肪は、体温調節や運動能力の向上、聴力など様々な役割を持っている。

イルカの脂肪と同じ機能をもった素材を開発できれば、冬の海でも快適に泳げるスイムウェアを作ることができる。イルカのように水中の音を増幅できるようなスイムウェアが出来ると、より幻想的な海中散歩ができるかもしれない。医療の分野ではアキレス腱などを怪我した人の、新しい補助器具としてイルカの脂肪が役立つかもしれない。
