Scientists discover unusual biodiversity in the ocean at a depth of 4-8 km

Biodiversity at great depths of the ocean was much more significant than hitherto thought science. This conclusion was reached by researchers from the Institute of Zoology at the University of Cologne (Germany).

Scientists have published new scientific work, which evaluated the biodiversity in the deep Pacific and Atlantic Oceans. The data on which the study was based were collected over two decades.

“We analyzed sediments collected at depths of four to eight kilometers. The analysis allowed us to cultivate and sequence the genes of marine organisms that live at significant depths. It turned out that the biodiversity at depth is much higher than expected,” say the authors of the study.

The authors added that the bottom of the oceans at a depth of more than one kilometer covers more than sixty percent of the Earth’s surface area, that is, we are talking about the largest part of the biosphere of our planet. At great depths, as the scientists determined, live a wide variety of communities of creatures.

“On the bottom live mostly protists. Incredibly, their biodiversity far exceeds that of multicellular creatures. Our project showed that we still know very little about life on the bottom of the oceans,” conclude German zoologists.
