Within the echinoderms phyla, a total number of 87 luminous species are reported; this number represents less than 20f the total number of echinoderms species. Since 10 years, ophiuroids luminescence is the major subject of my research. Initial studies were conducted on the cosmopolitan species, Amphipholis squamata. New developments led us to study Amphiura filiformis, Ophiopsila aranea and Ophiopsila californica luminescences. Recently I have undertaken a survey of luminous status in ophiuroids from different part of the world. Three new species from Australia have to be added to the list of bioluminescent ophiuroids. Taking into account the recent discovery of a new luminous Californian ophiuroid (undescribed amphiurid species) it is suggested that bioluminescence in ophiuroids is more widespread than initially though. These new findings raise questions about the functional importance of bioluminescence in ophiuroids.
