Hello, this is Totti. Starting today, I changed to a thicker wetsuit. It's autumn in Miyakojima! Autumn is the season for sports, appetite, reading, and yakiniku. It's also autumn for travel and material desires.
Hmm, it seems like there are some strange ones mixed in, but anyway, it's autumn and it's the season for diving!
It's common for autumn to come suddenly after a typhoon, and the water temperature drops and remains low compared to midsummer. If you're wearing a thin suit, it can be a bit chilly after exiting on cloudy days.
Instead, the sea in Miyakojima is in full swing!
After a typhoon, there are changes in living things too.
It's normal for resident creatures to disappear, and it's a sudden farewell to the creatures I introduced every day. I wish I could have at least said goodbye.
On the other hand, there are also sudden encounters that make you think, "Wow, I didn't see this guy here before!" In human terms, partings and reunions are in the spring, but in the water, it seems to be autumn.
The breakup is always sudden
A large school of golden-striped tuna at a certain point. This was the spot I was planning to visit this fall as a highlight, and I was anxious about diving there for the first time since the typhoon. I also had to tone down the briefing.
I went to take a look, wondering if they were there or not.

There he was!!!
Their numbers haven't decreased, so it's a good feeling. I'm relieved that their separation is still a little ways off. By the way, I wonder how they all change their habitat at the same time. There doesn't seem to be a leader, so I wonder if they consult with each other.
By the way, it seems that golden-spotted fish leave their habitat at night and scatter to feed on sea fireflies and small shrimp. It's amazing how they manage to return to the same place every night.
And so partings and meetings came together.
I went to see a large school of cardinalfish, thinking, "Huh, let's see, it's those guys next." They were still a school of young cardinalfish, and each one was quite small, so from a distance they looked like smoke floating in the air.

This is a photo from the other day. Just like before, I took a peek to see if they were there, but something seemed strange. It wasn't them. It was a different one!

No, no, no, it's there but it's been replaced by a completely different fish!! Goodbye to the unexpected cardinalfish! Welcome to the golden-spotted cardinalfish!
Moreover, the school was roughly four times larger. When I saw the golden-spotted squirming in the darkness, I was thrilled because it looked like an incredibly large creature. It was the biggest shock I've seen all season!

I wanted to pull back and take a full shot, but this was the limit. Even with a 2500 lumen light, if I pulled back any further, the photo would be unpostable.
Next, let's use two strobe lights to kill them. Actually, this is only half of the group. It's scary, right? They move as a mass. It's a little scary. Scary, but amazing.
So, we have added another point to focus on. We will be announcing it as a limited special point for a limited time only, so please look forward to it.
If I say that and I'm not there tomorrow, just laugh at me.
Nice holiday! Big holiday!
I want a new camera. See you tomorrow!
