10 April 1968, Canada
Narwhal, Monodon monoceros
design: John Alexander Crosby

This image, again showing below and above the sea – looks cool, too.  Narwhals are living in the Northern sea, where icebergs are floating around.  The long tusk is a sensory organ to detect temperature and atmospheric pressure.. amazing!

水中と水面の上を描いている、さらに涼しげな一枚をカナダから。イッカクは氷山の浮かぶ北極圏だけに棲んでいるようです。歯が変形した長い牙は、気圧や温度変化を感知する高度な感覚器だって。うーん、すごい。
