4 black eggs appeared from the heart of the dark ocean, and inside them were aliens

  • During a robotic exploration of the deep ocean, scientists discovered never-before-seen jet-black eggs stuck to a rock.

  • After further study and DNA examination, the team discovered that the eggs belonged to a flatworm – an animal usually associated with shallow waters – that was previously unknown to science.

  • Although they live in a much deeper environment, preliminary research has concluded that this type of flatworm is superficially similar to its shallow-water relatives.


A common expression among oceanographers and others who explore the depths of the Earth’s waters It is that we are humans “I know the surface of Mars better than we do Ocean floors“The oceans cover more than 70% of the world’s surface, and are difficult to study, not to mention largely inhospitable to any creatures without gills.

As an example, scientists from the University of Tokyo and Hokkaido University in Japan recently found some mysterious jet black eggs while driving a remotely operated vehicle (ROV) in space. The Pacific Ocean At a depth of about 6,200 meters (or 3.85 miles). This is the maximum depth of the abyssal zone, the deepest layer in most oceans—the abyssal zones are technically deeper, but they only fill deep trenches. Any biological discovery in this area is extremely important, as the life cycles of the organisms that live there are largely unknown.



Unsure of the nature of these eggs, Yasunori Kano, a marine researcher at the University of Tokyo, who was controlling the spacecraft at the time, chose to retrieve a sample of the eggs. egg For further analysis above.

Although most of the eggs were torn and empty, at least four remained intact, and Kano sent these samples undisturbed to a team of… Invertebrates Biologists at Hokkaido University. After taking a closer look, the team realized that these “eggs” were actually cocoons containing a handful of flatworms.

“When I first saw them, I had never seen them before Flatworm “The cocoons (and I didn’t know what cocoons looked like), I thought they might be protozoans or something,” said Keiichi Kakuei of Hokkaido University, who co-authored a study on the discovery in the journal. Biology lettersTell IFLScience. “Under a stereo microscope, I cut one of them, and something like a milky fluid leaked out of it; After blowing out the milky thing with a straw, I found white, fragile objects in the shell and realized for the first time that it was a cocoon of flatworms.



This was a particularly surprising discovery, because we know absolutely nothing about abyssal flatworms, and they have never been discovered at such great depths before. In fact, the deepest flatworm ever observed before this discovery was found at a depth of about 5,200 meters (3.23 miles). However, that sample was linked to a piece of… woodSo scientists cannot be sure whether the worms originated at that depth or sank there. Before that discovery, The deepest flatworm ever discovered It was found only about 2 miles away, according to Science Alert.

Yet further DNA Upon examination, the team confirmed that these creatures were a previously undescribed species from the phylum Flatworms. However, the paper also notes that although they represent “the deepest known record of free-living flatworms,” these deep-sea denizens superficially look like their shallow-water cousins ​​and show no radical differences in development.

While the ocean abyss Still shrouded in scientific ignorance, this discovery makes knowledge of these dark depths a little brighter.
