A Bit Windy, but Much More Comfortable Underwater!
We had some stronger westerly winds in Kushimoto today.
There were some waves on the surface, but the swell had gone down a lot!
Once underwater, there was hardly any movement, and with the water temperature close to 29°C, diving was very comfortable♪
Today, we went out for three fun dives with a guest from Japan!
An international guest was originally planning to join us in the afternoon, but unfortunately, due to a train delay, the dive had to be canceled.
We really hope to welcome them back to Kushimoto for diving another time!!
As if to show us that the swell had calmed down, lots of nudibranchs came out to greet us today.
When the swell is strong, they tend to hide in cracks and behind rocks, making them a little harder to find.
So, the number of nudibranchs we find can also be a good indicator of the swell.
Today, we found a tiny 1 mm Verconia subnivalis!
At this time of year, many of the Chromodorididae nudibranchs we find are still very small.
I actually spotted this one while looking for something else.
When you spend a lot of time looking for these creatures, even the really tiny ones somehow naturally catch your eye.lol
This nudibranch is popular for its cute shape, almost like a little stuffed toy. (^^)
Next was a slightly bigger 1 cm Produnga rubropunctata.
After looking at a 1 mm nudibranch first, 1 cm suddenly feels huge!
The tips of its cerata are especially beautiful.
With the microscope mode on a TG camera, you can take detailed photos, which makes identifying the species much easier. (^^)
The TG series is definitely a great tool for searching for nudibranchs!
Another new discovery today was finding out that there are multiple juvenile Regal angelfish in the area!!
I thought there was only one, but then we found another one on a different side. (^^;)
The same species often prefer similar environments, so it isn’t surprising to find more than one.
Now I’m wondering if there might actually be even more around!
The juvenile yellow boxfish, always popular among divers, was still there today.
However, it was in a very difficult spot to see.
Quick reflexes are important when trying to get a photo!!
They are often found in darker areas around rocks, so please be gentle with your lighting.
With the swell now settling down, conditions are becoming much better for macro photography!!
Westerly winds look set to continue for a while, but with the swell decreasing, boat diving should be able to go ahead as planned.
The weekend starts tomorrow, and we have lots of guests coming to dive with us!!
We’re looking forward to enjoying the waters of Kushimoto together with everyone visiting us!
Thankfully, we’ve also been receiving more inquiries for September and October over the past few days!!
Autumn is always an exciting season with a variety of marine life, and it looks like we may be able to enjoy that fun season for a little longer this year♪
