WOW!!! that is amazing, there so many answers to be found, but many more questions to be asked.

Breathtaking discovery..

There is still a long way ahead. This flash of light exhibited by this shark and other marine creatures is just the beginning, there are yet more to discover. Thanks to national geography resercher.

amazing...

Amazing,Facinating, we have much to learn

Holy SH*T!  You are SOOO lucky to be doing this & I for one am SOOO grateful you share it! Good luck on future adventures & discoveries. Keep diving,discovering & divulging! Thank you!!!

Our God is an Awesome God!!!!!!  Everything He creates is absolutely the best!!!!!!

So much yet to learn about the oceans , this will prove interesting 

omg.

Amazing!

That's amazing but why?

Awesome pictures but are all waters full of phospheresence. I remember as a child walking along the shores of the Annapolis River Basin on especially a warm moonlit evening and reaching down and picking up a handful of water and it would look like you were pouring liquid stardust. I don't ever remembering that happen all too often though. Perhaps the moon glow caused the reaction in the water. I just know how in awe I was at this beautiful discovery.   

Don't recall ever seeing any information about the bioflorescence  of ocean creatures before a couple of days ago.  Is this a new discovery?

Facinating, we have much to learn. WHY, are they biofluorescent!

me gusta es interesante y uno aprende sobre la naturaleza 

Darn, poor resolution!  Potentially great shots though.

Having dived in and around Western Australia I enjoyed my night diving.  But never seen the glowing marine life like these while carrying my camera and video units.

Just did my first dive at age 75.  Would love to get deep enough to see this - maybe later.

Take a dive into the pacific in the radiation path center, and see if you can glow too.

We may be able to understand the significance of this discovery in terms of benefit of the animals adaptation for survival. Is it a warning to predators to avoid them or a way to attract a mate? 

Scorpions are known to glow in the dark in the presence of black light. In order for animals to respond to black light, they must have the ability to generate black light to make the effect visible to them. So very likely it is a survival adaptation to attract mates and warn potential mating competitors to be aware of it's presence within the same species, If an animal of different species can detect it's presence, by glowing in the dark in the presence of black light source excitation, it is advertising to its predator to come and get me. It is thus counter productive. Does not benefit the animal to reveal itself to it's predator.

Absolutely mind blowing yet I imagine a very humbling experience. Thanks for sharing.

can't beat Mother Nature

amazing !

Amazing discovery and beautiful to see. Excellent work, keep it up. Look forward to seeing more

GOOD OLE MOTHER NATURE, SHE'S SO MUCH SMARTER THEN US PUNTY HUNANS, WE WILL NEVER UNDERSTAND THAT.

I give up the advertisement took 5 min to end, been watching now for another 10 min and it still havent started

Wonderful underwater views of special creatures.

Awesome!  What is the difference between fluorescent and photo-luminescent ?  I 

This looks interesting but it has so many pauses that it gets to be to much after awhile.

Awesome!

It is amazing indeed. I like they contribute to find new species of fish and other marine

creatures. The use of lighting and camera filters under the ocean is great. These discoveries

are very important for the scientific world.

Simply amazing.  Our scientists are always finding astonishing findings and National Geographic seems to be there to capture the discoveries and notify the world.  If not for National Geographic, how much would we not know?  Thank you!  

We put putted our sailboat at night to Catalina some 30 years ago - and when on watch I saw lots of fluorescent animals below - never guessed that some could have been rays or sharks.

I never knew sharks had fluorescent colors on them.

That was the most amazing video about sharks i have since in a while,You guy rock.

This is amazing!

I want to watch alien attack and I can't get it,why

@Sweetie Peetie go topside & take pix in sunlight & air if you want perfect resolution.  & then try to avoid fog!

@Brian Edwards Well...you couldn´t. Just as they explain - you would have to have proper equipment with filters for light of specific wavelenght. You can´t see the "glow" in normal flash light. Invest a fortune and try again ;)

@Diana Lorentz Lucky you, Diana.  You're very fortunate.  I'm almost 74 & don't expect to ever be able to do that.  Enjoy!
