In the experiment studying bioluminescence and the predation of copepods by fish, a control group of jars with bioluminescent dinoflagellates experienced a higher predation rate of copepods by stickleback fish than in the jars with nonbioluminescent dinoflagellates. This provided significant evidence that

Bioluminescence may be defined as the production as well as the emission of light by any living organisms. Mainly the marine organisms emits light and attracts other insects for predation.

In the experiment given in the context, the controlled jars with bioluminescent dinoflagellates shows a higher rate of predation than the nonbioluminescent dinoflagellates proves that the dinoflagellates can avoid being eaten by the increasing flashing and they attract other predators to eat the copepods which swims near them. This is because the it is given that the predation is more in the presence of bioluminesence.
