Is that an unretouched photo? If it is, it's one of the most remarkable pictures I've ever seen.

Looks like a normal no moon night on the beach on Koh Jum. We paint each others faces and bodies by finger painting the phosphorescence. Lasts for 20 min or so and then you do it again. The drying squid ,having eaten the plankton does the same glow, enough to read by in a tent.

Try flushing the head in dark.

Wow!

LOL inquiring minds would love to know how you know a drying squid casts sufficient light to read by in a tent?

Dorado are so fast they're hard to harpoon in day light but at night you can see them swimming alongside in the phosphorescence Bingo.

Jerry, local fishermen catch and dry pla mok in Thailand .I was camping on Koh Surin when I found some squid forgotten on the rocks. They were very noticeable on a dark night so I took them into the tent and ta da , the discovery .Interestingly it wasn't a steady glow but rather a pulsing as if the squid or the plankton were communicating with each other . I thought you'd be more interested in the late night body painting

We frequently see a similar phenomena in the Gulf of Mexico on our annual trips to Key West and points south. My girls like to ride the bow (with tethers to jack-lines and life-jackets) when the weather's nice and a wave splash will sometimes leave them laughing and glowing. My better half calls it the "glow of good health".

Many more years ago than I care to think about.....spring break on South Padre....an accident in Port Isabel knocked out power to the island. We all ran down to the beach (as did thousands of others) and started partying in the dark. The waves would explode in greenish light, the foam washing up on the beach glowed, and everywhere you stepped, bright green sparks would flash and branch out under your feet.

A few hours later, power was restored....lights came back on....and the show was over.

I'm skeptical. What's that glowing thing on the horizon? Is it really possible to get such a clear sky with things glowing on the horizon?

Also if it's really a moonless night, how is the shadow explained? Why is the sand so bright?

And how do you get a photo of water on a beach at night with such detail and no blurring due to the long exposure times required?
