Uh...definitely not firefly squid...some kind of jellyfish...you can see the bell of the jellyfish and the long tentacles...But very cool anyway!
Amazing.I'm always looking for phosphorescence or bioluminesence during night walks at the beach. Seeing something like this would be outstanding.
Dave here.They are Firefly Squid in Toyama Bay Japan.More info:http://tolweb.org/Watasenia_scintillans/19645
Thanks, Dave. With those key words I was able to find additional photos here -http://www.amusingplanet.com/2012/03/firefly-squids-in-toyama-bay-japan.htmlBut I have to agree with Daniel that the tentacles in the embedded photo appear to be too long to be those of squid, and look more like some type of bioluminescent jelly.
