A Beautiful Bobbing Nudibranch

Occurred on December 13, 2022 / Ishigaki Island, Okinawa, Japan

Info from Licensor: "I entered the sea in winter. Compared to summer, there were fewer creatures and fewer species. The weather was not good. The wind became stronger and the water flowed faster. The sun shone temporarily and it became brighter. There was a small nudibranch. It was a very common species. But it shone brightly and was very beautiful. Its small body was swaying in the water current."
