It was raining in the morning, and the wind turned from the east to the south, and then to the west in the afternoon.

But it wasn’t too windy, so we went to the west side of Ishigaki.

How was it?

It was beautiful!!!


Visibility was great, and the water was soooo blue!


It felt a bit cold in the water as the ground temperature was not so high, but the corals are doing great!


They look a lot more lively and healthier than the last year 🙂


Unfortunately there was no manta at the cleaning station, but some of the teams saw a manta passing by.

We saw a manta feeding on planktons around Osaki area though.


And Osaki was full of beautiful sea life!


An Octopus was curiously looking around…


A Trumpetfish.


Disco clam.


And the highlight of the day…

Giant cuttlefish!

Yes, it is the season!

We saw six of them around the area, and saw some males fighting for a female!


Once the cuttlefish left after laying eggs in the corals, this Threadfin butterflyfish came to feed on their eggs 🙁

Well, this is nature…


Rainy day is over now, and it is forecasted to be sunny tomorrow 🙂
