Our dive cruise today was around Osaki and Kabira area of Ishigaki. Unfortunately there was no manta today but there was a huge school of Big mouth mackerel hovering around the cleaning staiton!


While we were waiting for Mantas, we saw some big cloud approaching us from far away. when the cloud started to cover us, we found out it was a huge school of Big mouth mackerel! That was a huge cloud, and there must have been millions of Big mouth mackerel! We sometimes see much smaller school, but this one was exceptional. Check out the video clip on our Facebook page!


When we looked down, there was a school of Barhead spinefoot 🙂


We saw lots of things around Osaki, too. Crocodilefish has multiple facial expression from different angles.



Our guest from Astrid successfully completed her OWD course! Congratulations!

Enjoy your trip to Kyushu!


Hope to dive with everyone again!
