Researchers from China’s 40th Antarctic scientific expedition team have highlighted the crucial role of the luminous lanternfish, scientifically known as Electona antarctica, in the Antarctic ecosystem. This species, extensively distributed in the sea areas surrounding the continent, boasts a luminous body fully covered by light-emitting organs, growing to approximately seven or eight centimeters in length.
Renowned as a representative of pelagic fish residing in ocean depths ranging from 200 to 1,000 meters, the lanternfish belongs to the Myctophidae family. Among Antarctic pelagic fish, Myctophidae holds the largest population, with Electona antarctica being a standout member.
Liu Chunlin, a member of the expedition team and a doctoral student at the College of Aquatic Sciences of Ocean University of China, emphasized the enduring focus of scientific research on Myctophidae. Electona antarctica, in particular, plays a critical role in the food network and the overall Antarctic ecosystem due to its pervasive presence in the surrounding sea areas and substantial population.
Globally, there are about 32,000 fish species found in various oceans, while the Southern Ocean, where the expedition is taking place, has revealed just over 370 species. China’s fish survey commenced after the team reached the Amundsen Sea on Thursday, marking a significant step in advancing understanding and conservation efforts in the Antarctic marine environment.
