Scientists have got to the bottom of a 5-year mystery after finally identifying a tiny sea creature captured on camera in 2018. It is the latest in a series of oceanic discoveries and experts recently observed “zombie worms” devour an alligator in an incredible experiment. For the tiny creature, the baffling question of its identity took a team of zoologists and parasitic worm specialists to solve after the small creature was pictured by an underwater photographer in 2018 off the coast of Okinawa in Japan. After photographer Ryo Minemizu captured the image, he shared it on social media asking the hive mind if they knew what the creature was, but everyone was left stumped. Minemizu was determined not to give up and instead went back to the area and was able to capture another ladybird-sized creature that was the same, or very similar, to the original one he had come across. The research team that was interested in identifying the sea creature approached him and Minemizu sent them the sample to research. Your browser does not support the video tag. Current Biology (2023) The team’s results were published in the Current Biology journal putting an end to the 5-year long mystery baffling experts. In a fascinating twist, the team found that the sample was not one, but two creatures that were clinging tightly to one another. Both were identified as types of cercariae parasitic larvae worms, with experts dubbing one as the “sailor” and the other as a “passenger” thanks to how they behave when they are connected. Passengers were much smaller than the sailors and when they were bonded together, they formed a flat-topped hemisphere shape. They squeeze their bodies together with heads facing the inside of the sphere, meanwhile, their tails latch onto one another. Experts believe the two individual creatures have created a colonial organism that suits both of their needs and according to the study's authors, “represents the first case of labor division in digenean larvae”.

Someone could soon be at risk of dying or being injured by a falling satellite every other year, according to a new report. By 2035, if SpaceX’s Starlink space internet satellites continue to grow in number, then they some 28,000 pieces of them will be falling from the sky each year, according to a report from the Federal Aviation Authority. The chance of one surviving its fall to the ground and injuring or killing someone would be 0.6 per year, it said – which would make it likely to happen once every two years. They could even pose a risk to aircraft, it said. The probability of an aircraft being downed by a satellite would be 0.0007 per year by 2035, the report claimed. The report was commissioned amid increasing concern about falling space debris, and the vast collection of material that has been put into space in recent years. Companies such as SpaceX are launching more and more satellites each years, and experts have warned that there is a danger of collisions both in space as well as on the ground. The new report aimed to evaluate the risk posed by that falling space debris. It also suggests that some of the danger could be limited with more regulation. But it notes that the FAA does not have any power over launches that happen outside of the US. As with many of the problems in space, the world currently lacks an international approach to space debris, new satellites and the dangers that those objects might pose. The report primarily looked at the constellation of satellites that have been launched and are planned by SpaceX, for instance. The company has launched 5,000 such satellites already, and plans to increase that dramatically, and SpaceX represents over 85 per cent of the risk posed to people on the ground, the FAA’s report said. But it did not look at other networks of satellites planned in other countries. Recent reports have suggested that China is planning its own huge constellation of satellites that will also offer their own space internet, named Guowang, for example. SpaceX has said that the analysis used to calculate the number is “deeply flawed” and based on false assumptions about the danger posed by its satellites. The company’s satellites are more likely to burn up on entry than the report assumed, the company’s principal engineer David Goldstein wrote in a letter to the FAA, according to a report from Space News.
