It was cloudy and maybe the ground temperature was a touch lower than yesterday, but it was hot nonetheless – we were all of a sweat by the time we welcomed our guests. Once out on the water, however, it was much cooler with nice ocean breeze!


We only had four guests on the boat today, and we cruised around our standard course of Ishigaki. Millions of Luminous cardinalfish covering reefs and corals is a typical underwater scenery of summer around Ishigaki area 🙂


Expert diver team went down deep, looking for some interesting sea life. It was cloudy and a bit dark, and this Mandarinfish might have thought it was night time – it was almost coming out from its house. Can’t hide if you are so colorful!


Peacock mantis shrimp is also very colorful.


Spotted prawn-goby has eyes that look like soccer balls.


After long lunch break, we cruised to Manta city. Although we waited for a long time, unfortunately there was no manta today. So we had a lesson on making bubble rings 🙂


Diving is all about nature… We can dive at the manta point only when the condition is good, but this doesn’t mean there will be manta always 🙁

Blue Swan will be on maintenance tomorrow, and we will be joining our neighbor boat for our dive cruise.
