Scientists captured images of a glow-in-the-dark shark in New Zealand for the first time. Dalatias licha, a kitefin shark, is the world’s largest bioluminescent vertebrate, which can grow up to six feet long. As told by researchers from the Catholic University of Louvain (UCLouvain) and the National Institute of Water and Atmospheric Research (NIWA), the fish was found in the Chatham Rise, above South Island’s east coast.

Out of the 540 known shark species, 57 can produce light by biochemical reaction, UCLouvain’s head of the marine biology laboratory, Dr. Jérôme Mallefet explained. Mallefet added that kitefins are “really difficult to observe” as they live within 200 and 900 meters under the ocean floor. Bioluminescence was also witnessed in southern lanternshark (Etmopterus granulosus) and blackbelly lanternshark (Etmopterus lucifer).
