there is a jellyfish the makes an protien that produces green fluorescent glow. This protien is used in genetics as a marker and also has been used to create transgenic mice that glow green. I believe the protien is called GFP simply for green flourescent protien.

The most obvious one is fireflies. But there are also bacteria, squid, some fish (particularly the deep-water ones), and an oceanic plankton (you can see them light up dimly as ships plow through the water at night and sometimes during storms).
Most of these creatures make use of a modified pigment called 'luciferin', which comes in a variety of different specific types.

Firefly or renilla luciferase are not fluorescent proteins, luciferin when enzymatically cleaved by luciferase will fluoresce. GFP is a fluorescent protein.
