A protein found in jellyfish which fluoresces, or glows green visible light when excited by UV light with a wavelength of 395 nanometres.

It can function as a biological marker when attached to other proteins. The structure of the protein is cylindrical with the glowing component, an amino acid complex called a fluorophore, in the middle of it.
