Mesopelagic fishes like lantern fishes (Myctophidae) and cyclothonids (Gonostomatidae) live in the twilight zone of the ocean, between 200 and 1,000 meters deep. With a stock estimated at 1,000 million tons so far, mesopelagic fish dominate the total biomass of fish in the ocean and are the most numerous vertebrates of the biosphere. Now it turns out they have been severely underestimated. Researchers writing in Nature Communications have estimated their numbers are 10 times higher than previous estimated, based on acoustic observations conducted during the circumnavigation of the Malaspina Expedition. read more
