Emulate some species of jellyfish (4)

I believe the answer is:

glow

(Other definitions for glow that I've seen before include "Emit light and heat without flame" , "Shine steadily and brightly" , "Give out steady light" , "Give out light without flame" , "Shine, maybe in dark" .)

I've seen this clue in the LA Times.
