It is likely that bioluminescence in the dogfish shark is valuable either as protection, for luring potential prey, or for finding sexual partners. Researchers have studied the phylogeny of the dogfish shark in order to learn more about the origins of bioluminescence in deep-sea creatures.

Bioluminescence helps us further our understanding of the origins of the vast majority of marine life.
