Ocean is Glowing because of Bioluminescence, which is one of the coolest things we have seen. Imagine being on a beach at night, and watching the waves crash against the shore, glowing bright blue in the dark. If you were to enter the water, the glow would be localized around your body, wherever you disturb the micro-organisms, making you feel like a magical being.
The best spot to see it in action is Laguna Grande, a bay on the northeastern corner of Puerto Rico. Every splash makes the water flash, and darting fish create lightning bolts in the deep.
