This is official site of Black Water Dive® produced by photographer Ryo Minemizu. Black Water Dive® is a kind of night diving. We are setting up underwater lights of high-color rendering on the sea bottom of night that while considering tides, times, places. The creature which appears is mainly juveniles and larvae. All is fascinating, and it's not to be seen at daytime or regular night diving. It will be your first experience. This site will introduce the state of the event and the creatures seen and also future of BWD schedules. *"BWD"stands for Black Water Dive®.*Black Water Dive® is a registered trademark of Ryo Minemizu.

The little record about Juvenile Vinciguerria attenuata (Cocco, 1838) Phosichthyidae from Suruga Bay in Japan.

Vinciguerria attenuata swim at mesopelagic on daytime and come to epipelagic on night time. They has many photophore on the ventral abdomen for Counter-illumination. I am meeting that many times at Black water Dive®. But, with respect to the Juvenile I can be counted on the fingers of one hand. I met that daytime at surface about 0.5m to recently and It's only 1m from the shore.
It seemed that little bit weakened.
That the sea temperature was 19 degrees.
