Glowing Waves Are Caused by Tiny Plankton

Green fluorescent protein, first isolated from the jellyfish Aequorea victoria, became a key tool for tracking molecules in living cells.

In the open ocean's deep waters, bioluminescence is so common that a majority of animals are thought to produce light.

Deep-sea anglerfish carry a light-producing lure, and its glow comes from symbiotic bacteria living inside it.

The reaction is extremely efficient and produces almost no heat, which is why the light is often called cold light.
