The spawning of "Amami Hoshizorafugu", which inhabits only the sea near Amami Oshima in Kagoshima Prefecture and has a unique habit of drawing a pattern like a crop circle on the sandy seabed, has been confirmed, and a mysterious sight has spread. ..
A crop circle-like pattern with a diameter of about 2 meters was confirmed on the sandy seabed at a depth of 27 meters in the Oshima Strait between Amami Oshima and Kakeromajima in Kagoshima Prefecture.
Katsuki Ko, who is studying marine life on Amami Oshima, succeeded in shooting in the middle of this month.
This pattern is made by "Amami Hoshizorafugu", which was announced as a new species eight years ago, which is a kind of rare puffer that lives only in the sea near Amami Oshima.
Males have a unique habit of creating radial patterns on the sandy bottom of the sea, which is said to have the role of attracting females and protecting eggs from the flow of tides.
The video also shows a female drawn to a stunning geometric pattern rubbing her body against a male to lay eggs.
Eggs hatch about a week later, during which time the males continue to protect the eggs.
The breeding season of Amami Hoshizorafugu is from April to July, and it will reach its peak from now on, so Mr. Xing said, "I was relieved to see the beautiful and mysterious spawning bed. It is a treasure of the island that represents the diversity of the island, so I would like to continue to watch over it. "
