It is Saturday today. However, the weather was so bad. It was raining heavily. The winds blew violently as well. Like I said before, it is the rainy season now. After working the night-shigt, I decided to visit 美ら海aquarium because it wasn’t affected by the weather. Tyuraumi Aquarium is famous for its Kuroshio water tank because there are whale sharks in it. You can see how sharks eat. Whale sharks eat krill by inhaling one ton of water. It was much more dynamic than I had expected. They can filter them using their gills. If they swallow a fish, they usually exhaled it back out because they don’t usually eat it. However, the guide there said that there are no krill in Okinawa. It is not yet clear how whales live in the wild.
After that, I went to see a dolphin show. It was held as scheduled although the heavy rain and strong wind were continuing. The dolphins completed the show as usual in spite of the bad weather. I don’t know why but we are always attracted to dolphins.
