According to Gruber and Sparks (2015), [[fluorescence]] is observed in an increasing number of marine creatures ([[cnidarian]]s, [[Ctenophora|ctenophores]], [[annelid]]s, [[arthropod]]s, and [[chordate]]s) and is now also considered to be widespread in [[Chondrichthyes|cartilaginous]] and [[Actinopterygii|ray-finned]] fishes.<ref name=Gruber_2015/>

The two [[Marine biology|marine biologists]] accidentally made the observation in the [[Solomon Islands]] on a hawksbill sea turtle, one of the rarest and most endangered sea turtle species in the ocean, during a night dive aimed to film the [[biofluorescence]] emitted by small [[shark]]s and [[coral reef]]s. The role of biofluorescence in marine organisms is often attributed to a strategy for attracting prey or perhaps a way to communicate. It could also serve as a way of defense or [[camouflage]] for the sea turtle hiding during night amongst other fluorescent organisms like corals. Fluorescent corals and sea creatures are best observed during night dives with a blue [[Light emitting diode|LED]] light and with a camera equipped with an orange [[optical filter]] to capture only the fluorescence light.<ref>{{cite web| last = Lee| first = Jane J.| title = Exclusive video: first "glowing" sea turtle found| work = National Geographic News| access-date = 2017-03-19| date = 2015-09-28| url = http://news.nationalgeographic.com/2015/09/150928-sea-turtles-hawksbill-glowing-biofluorescence-coral-reef-ocean-animals-science150928-sea-turtles-hawksbill-glowing-biofluorescence-coral-reef-ocean-animals-science/| archive-url = https://web.archive.org/web/20150930220119/http://news.nationalgeographic.com/2015/09/150928-sea-turtles-hawksbill-glowing-biofluorescence-coral-reef-ocean-animals-science150928-sea-turtles-hawksbill-glowing-biofluorescence-coral-reef-ocean-animals-science/| url-status = dead| archive-date = September 30, 2015}}</ref><ref>{{Cite news| last = Hanson| first = Hilary| title = Scientists discover 'glowing' sea turtle| work = Huffington Post| date = 2015-09-29| access-date = 2017-03-19| url = http://www.huffingtonpost.com/entry/sea-turtle-glowing-discovery_us_560ac2a0e4b0dd8503094fd4}}</ref>
