While snorkeling, I was surprised to see a glowing comb-jelly drifting past the coral.

A comb jelly drifted through the moonlit tide, its shimmering ctene rows scattering light like tiny mirrors.

Late at night, biologists observed a glowing swarm of comb-jellies drifting near the kelp forest.

comb jellies often glow as they drift through the dark waters at night.
