The researchers studied bioluminescence in deep-sea organisms to understand how it evolved.

On summer nights, coastal researchers documented several rare bioluminescences along the shoreline, each shimmering in a different hue.

The jellyfish drifted bioluminescently through the dark water, leaving faint trails of light.

At night the tiny plankton bioluminesce, turning the waves into a field of stars.

Tourists gathered on the beach to watch the bioluminescent waves shimmer under the stars.
