- Magic Sea Water! Why does it sparkle? This is the story of why the sea sparkles blue in summer nights. Follow me along to a tiny Japanese island surrounded by glowing waters. See with your own eyes what causes sea sparkle and meet the mysterious Dinoflagellate Noctiluca scintillans under the microscope.

Beautiful eye must get a bottle of them .x
I haven't seen it, but my dad used to tell me stories about it.
He grew up in southern California along the coast, and he said that at certain times of the year if he went to the beach right after the tide went out there'd be these "organisms" in the water would emit a blue light when disturbed. He and his two brothers would walk along the still sopping wet sand and they'd leave these very distinctly blue footsteps. He always described it as very magical experience. I've heard the story many times, though he's not around to tell it anymore. This was really neat. Never thought I'd get to see the organism behind it all. Thank you for posting this.
This organism isnt that rare, but you need good conditions to spot them. If you are on the beach after a warm day on a dark night you have a good chance of finding some. I found i can always find some in the sand on beach, go right up to the water and you can find them if you disturd the sand.
My condolences on the loss of your dad. Thank you for sharing his story of the magical footprints. Childhood is so full of wonder and magic already, but that experience would take it to a whole new level. I'm glad he had the chance to see that. ❤
It is sea sparkle
very informative and wonderful video...from bangladesh
Thanx so so much I am in school and I’m learning about sea sparkle so thanx I needed information and now I have it?
No one cares about it
Thank you so much for for posting such a interesting video , I want to know about, How the Noctiluca preserve seeds in winter?
That's great video. Do you know where may I get some online in the USA?
Will this last for long? In bottle
Hey... Great vid... Can i ask what microscope you use so capture all your cool videos..
I think its just planktons who gaves us oxygen
I have seen this phenomenon and swam in it and the key is not that the organisms conglomerate and only one place they are all over the kids that they only light up when agitated so if the water is still you won't see them
I'd like to know where I can buy 20 liters of those, and if they can be bred commercially or are even able to survive and multiply in a private pond.
I suspect the light is produced to ward off predators. Since they're aquatic, it seems safe to suggest that macroscopic threats that may eat them would disrupt the water around them enough to trigger bioluminescence, which may then freak those threats out and make them look elsewhere.
The idea that they're warning each other is interesting as well (sounds similar to Quorum Sensing) though I suspect that would be more successful if it involved the release of some manner of "stress" chemical which can be recieved by each member of the swarm.
I'm very curious about what converts the mechanical energy of the waves into an activation signal for the bioluminescence. Whether there's quick gene upregulation involved or if it's just naturally present conjugate molecules that can only interact when disturbed.
Cool theory
*Nomadic Nostoc* the content you have is very informative! keep it up! thumbs up if u believe me!
Since these organisms cannot control their own movement, could the light attract their prey species and attract food for them? Thank you!
It!
Noctiluca wow, i student i from vietnam
