Juniper Publishers - Journal of Oceanography Introduction Bioluminescence is a amazing biological phenomen, which can be found in terrestrial and oceanic environments. Numerous bioluminescent taxa were described from the marine environment [ 1 - 2 ]. Bioluminescence is especially abundant in the deep-sea. The majority of luminescent taxa are invertebrate animals. In contrast to the high diversity in invertebrates, vertebrates lack bioluminescent light organs, with the exception of an amazing diversity in teleosts and some shark species. A recent paper reported that bioluminescence appeared in ray finned fishes in 27 independent evolutionary events [ 3 ]. Bioluminescent light is generated in spezialized light organs based on a oxyidation of a light emitting luciferine in the presence of oxygene and the enzyme luciferin [ 1 , 4 ]. Most of the bioluminescent species produce blue green light in the wavelength range around Xmax ~475nm [ 1 ]. Luminescence in fishes c
