Why is the ocean glowing like this?

Because it’s home to billions of microscopic creatures called Pyrodinium bahamense that shine when disturbed – a phenomenon called bioluminescence. 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.

Sea creatures glow primarily to communicate, defend themselves, and sometimes attract prey. In most parts of the ocean, especially the deeper areas, bioluminescence is the only kind of light ever seen.

Larger glowing denizens of the deep include jellyfish, many types of squid, flashlight fish, hatchetfish, dragonfish, and anglerfish. Other underwater light sources include ribbon worms, copepods, and at least one type of clam.
