Photos of a glow-in-the-dark shark were shot for the first time by scientists. Dalatias licha, a kitefin shark, is the world’s most massive bioluminescent vertebrate, which grows to almost six feet long. As reported by researchers from the Catholic University of Louvain (UCLouvain) and the National Institute of Water and Atmospheric Research (NIWA), scientists found the fish in the ocean of Chatham Rise, over the east coast of South Island in New Zealand.
Dr. Jérôme Mallefet, head of the marine biology laboratory at UCLouvain, explained that about 57 of the 540 known shark species can emit light through biochemical reaction, completing the process of bioluminescence. Despite being the slowest swimming shark species in the world, Mallefet said that kitefins are “really difficult to observe” as they exist between 200 and 900 meters beneath the oceanbottom. Two other species of the same kind, Etmopterus granulosus (southern lanternshark) and Etmopterus lucifer (blackbelly lanternshark), were also documented executing bioluminescence.
