bioluminescence.noun
emission of visible light by living organisms such as the firefly and various fish, fungi, bacteria such as those that travel on the Anglerfish. To produce this light oxygen, a molecule called luciferin and luciferase is required. The oxygen and luciferin produce the light, and luciferase, an enzyme slows the reaction produced by the other two down, so that all the molecules fire at once producing a flash! Luciferase is a mystery!

Marine biologist Jean-Francois Rees of the Catholic University of Louvain in Belgium says that."...animals can't produce the molecules for bioluminescence by themselves. Its origin is a mystery. Somebody somewhere in the marine environment is making it, but nobody knows who."

The potency produced by the oxygen and the luciferin isn't necessary for light production, and without the inhibitive luciferase, the chemical reaction would be used up far too quickly. All three components are necessary to produce this defensive mechanism. If they didn't exist simultaneously, deep sea life relying upon bioluminescence would have been quickly eradicated.

There is no plausible answer other than God planned a system to ensure that they would be around for a long while.

Bioluminescence is common in deep sea animals.
