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.
True or False:
- Dalatias licha is the world’s smallest bioluminescent vertebrate.
- Chemoluminescence refers to the process of emitting light through biochemical reaction.
- The first glow-in-the-dark shark was documented in the Atlantic Ocean.
- Kitefin sharks are difficult to observe because of their depth beneath the ocean’s surface.
- As stated in the article, southern lanternshark and blackbelly lanternshark were also reported doing bioluminescence.
