The Typhoon Hasn’t Had a Major Impact Yet — 3 Boat Dives in Kushimoto!
Typhoon No. 25 is currently approaching Japan. Today, there was some swell, but the conditions were still good enough for diving.
Visibility was around 8–10m, and the water temperature was 26°C. Despite the swell, the water was surprisingly clear♪
Just before the typhoon’s closest approach, we went fun diving with a guest from Venezuela and a guest from Japan.
Our guest from Venezuela was our very first guest from South America!
So far, we have welcomed guests from North America, South America, Oceania, and Eurasia.
Now we just need a guest from Africa!! (^^)
Anyway, back to the underwater world.
Many of our guests today love nudibranchs, so we mainly focused on finding them during our dives.
Our guest told us that they don’t often see such tiny nudibranchs in the warm, clear waters of South America.
So, the extremely small nudibranchs we find in Japan seemed very interesting to them.
First, we found a Verconia subnivalis that was around 1mm in size.
Our guest observed it very closely, so it was definitely worth finding such a tiny one! (^^)
And the tiny nudibranchs continued.
Recently, we have also been seeing Chromodoris orientalis quite often, even though we don’t usually see them very much on our boat dives.
This one was a little bigger at around 5mm. After starting with a 1mm nudibranch, even 5mm felt big! haha
Of course, they weren’t all extremely tiny!!
We also found Goniobranchus kuniei in the same place as yesterday.
Hopefully, it will stay around the same spot for a while!! The gills of this nudibranch are especially beautiful.
If you get the chance, try taking a close-up photo!
On our last dive, there were lots of Goniobranchus geometricus!! We kept finding them everywhere today!
This year, it feels like the most common nudibranch species have been changing depending on the season.
Right now, it seems to be the season for Goniobranchus geometricus.
Finally, we went back to another extremely tiny nudibranch.
This one was also around 2mm in size. It was so small that the color on its rhinophores didn’t seem to have developed yet.
After looking into it, I think it may be a Eubranchus sp.1.
While writing this blog, I realized that today really was all about nudibranchs!
Can you tell from these photos just how many nudibranchs we are seeing right now??
The diving conditions during Japan’s Silver Week holiday haven’t been ideal because of the typhoon, so we are especially grateful to all the guests who still came to dive with us.
We have also been receiving more inquiries from overseas guests since this week!!
From October, Uchiura Beach in Sue will also open, giving us even more diving options alongside the abundant marine life of Kushimoto.
We look forward to welcoming you for fun diving, Discover Scuba Diving, and diving courses!!
If you would like to dive at Uchiura Beach in Sue, please let us know when making your reservation.
