We searched for ascidian on Kumejima Island
for Sasaki-san's master thesis research. |

We went snorkeling and discovered several
types of ascidian. Even in Okinawa, the sea
was cold in late October. |

Next, we investigated the reefal microbial
crust contained in typhoon stones. It is
said that large rock masses like this are
carried by typhoons. |

We also searched for ascidian on the main
island of Okinawa, but perhaps because it
was the wrong season, we couldn't find any.
By the way, a large amount of pumice from
Fukutoku Okanoba had washed up on the shore. |
