New Unknown Creatures Discovered on the Seafloor

The depths of the oceans have been a source of curiosity for people for centuries, at least as much as the depths of space. still undiscovered in the oceans of the world keeping the mystery there are many spots and there are many as yet unknown living in these places. species Of course, every research on the oceans is interesting.

Researchers who want to shed some light on this mystery about the oceans that have been going on since the existence of humanity, examined the ocean floor in hundreds of different parts of the world. As a result of this research, the research team discovered that microscopic life evolved in the deepest and darkest parts of our planet. astonishing variety achieved revealing results.

The depths of the ocean have three times the diversity of life than the surface of the ocean

the surface of our planet more than half The fact that the deep ocean sediment that covers it is difficult to reach means we have almost no idea what is going on in the ocean depths where this sediment is found. Although we have discovered a very small part of the deep sea in recent years, thanks to remote controlled vehicles, even this small part that has been discovered is in the depths. a world It was enough to show us that it is, but even more so.

Within the scope of the new research, sediment samples collected from different parts of the world, sea creatures poured on the sea floor while continuing their lives. environmental DNA (eDNA) were analyzed for. Examining this eDNA shed by sea creatures, researchers also found traces of microbes and other small creatures that make up the ecosystem under the sea floor.

Comparing the results obtained here with other existing DNA data of plankton collected from the upper layers of the ocean, the researchers are confident that the new data belong only to living things in the deep; As a result, most eukaryotic organisms living on the ocean floor have been recognized by modern science. that you don’t know they discovered. In fact, it seems that the bottom of the ocean is higher than the upper waters. at least three times host a greater diversity of microbial life.

Geneticist Jan Pawlowski of the University of Geneva in Switzerland, who was one of the research team that brought together such a globally consistent molecular dataset of the ocean world for the first time, said: “We compared our deep-sea benthic DNA sequences with all available reference sequences for known eukaryotes.” saves as. The obtained data show that approximately two-thirds of the benthic diversity belongs to any known group. cannot be appointed Pawlowski stated that this shows a great importance in our knowledge of marine biodiversity. space conveys what it means.

The data obtained show that there are also larger unknown creatures on the sea floor.

The diversity of plankton found, although current analysis mostly focused on smaller sized organisms such as diatoms and dinoflagellates and small animals such as earthworms and small mollusks; the deep sea is also more to big animals presents some other evidence that it is also a host.

The authors of the study“These deep ocean sedimentary communities include not only taxa known to be important drivers of the biological carbon pump, but also diverse taxonomic and functional groups from arguably the most fundamental ecological processes of the world ocean.” and the results show that the deep ocean sediment richest modern ecosystem and underlines that it is one of the fossil archives.

Despite warnings from marine scientists that we need comprehensive ecological risk assessments first commercial deep sea miningincreasing and how many lives are in this situation. in danger Given that this is so, the researchers call for further exploration of the seafloor to better understand and protect these deep-sea ecosystems.
