During an insect survey on the coast, I was utterly astonished to discover a whale, about 2 metres long, stranded at the water’s edge. I immediately contacted the local government and a whale expert, and was informed it was a Risso’s dolphin (Grampus griseus). It is said that the Japanese name "Flower" derives from the white marks on its body, which were caused by other individuals or squid. Although it looked quite weak and in a serious condition, the sheer power of its movements—flapping its fins and spouting water from time to time—was truly magnificent. Since an expert would be managing the situation, I left the place. However, I couldn’t tell whether it was the sound of breathing or a cry, but the low ‘boo’ sound the whale made kept echoing in my head long afterwards.
海岸で昆虫調査中、波打ち際に体長2mほどの生きたクジラが横たわっているのを見つけて仰天。 すぐに自治体と専門家の方に連絡すると、ハナゴンドウと教えて頂く。和名の「ハナ」は、他個体やイカなどにつけられてできる体の白い傷が由来とのこと。 かなり弱っていたけれど、ヒレをばたつかせたり、潮を吹いたりする動きの力強さは、やはりクジラのすごい迫力。 専門家の方にご対応頂けるということで、私はその場を離れたものの、呼吸の音なのか、鳴き声なのか、クジラの発する「ボオッ」という低い音が、その後もずっと頭から離れずにいる。
