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 the Creator planned a system to ensure that they would be around for a long while.

Bioluminescence is common in deep sea animals.

Usage note: 'both' is used to indicate that the action or state.denoted by the verb applies individually to each of two entities (both books weigh more than five pounds, for example, means that each book weighs more than five pounds by itself, not that the two books weighed together come to more than five pounds). 'Both' is inappropriate where the verb does not apply to each of the entities by itself. In possessive constructions 'both' is usually preferred (the mothers of both, rather than both their mothers; the fault of both, rather than both their fault or both's fault). When both is used with 'and' to link parallel.elements in a sentence, the words or phrases that follow them should correspond grammatically (in both India and China or both in India and in China, not both in India and China).
