First-Known Sighting of a 'Massive' Antarctic Squid is Caught on Camera During Nat Geo Expedition

First-known sighting of living Antarctic squid Gonatus antarcticus, spotted by researchers on the National Geographic and Rolex Perpetual Planet Expedition in the Southern Ocean – Credit: ROV SuBastian / Schmidt Ocean InstituteResearchers have recorded a video sighting of a three-foot-long deep-sea squid species that’s never been filmed nor seen alive.Gonatus antarcticus squid, an elusive squid found only in the frigid waters around Antarctica, was discovered on Christmas Day by the Schmidt Ocean Institute’s research vessel, the R/V Falkor (too), in a surprise moment caught on camera via the research vessel’s remotely operated vehicle, SuBastian.Prior to the astonishing discovery, the species was only known from carcasses in fishing nets or when the squids’ beaks were found in the stomach of fished marine animals.Footage of the squid shows the animal with scratches on its arms and fresh-looking sucker marks on its mantle but otherwise shows it is in good shape. Spotted at a depth of approximately 2,152 meters—below 6,000 feet—in the Weddell Sea, researchers have not been able to confirm the squid’s sex from the footage, nor age, but the discovery is a reminder of how much more there is to learn about the relatively unexplored polar regions of our world’s ocean.Undertaken through the National Geographic and Rolex Perpetual Planet...

Scientists in Japan Develop Non-Toxic Plastic That Dissolves in Seawater Within Hours

Japanese scientists were thrilled to receive significant interest from the packaging industry over their new seawater-degradable plastic.Breaking apart into nutritious compounds for ocean-borne bacteria in just 2 to 3 hours depending on the size and thickness, the invention could be a major solution to reducing plastic waste in the environment.GNN has previously reported that the amount of plastic waste in the ocean is currently overestimated by 3,000%, making the remaining total a much-more addressable challenge.To that end, researchers at a lab in Wako city near Tokyo used two ionic monomers to form a salt bond for the basis of the polymer plastic. Despite being strong and flexible like normal petroleum-based plastics, the material is highly vulnerable to salt and immersion in salty ocean water dissolves the plastic in short order.Researchers from the RIKEN Center for Emergent Matter Science and the University of Tokyo who developed the plastic don’t have any detailed plans for commercialization, but they have been contacted by members of the packaging industry with significant interest.The plastic is non-toxic, non-flammable, and doesn’t emit CO2. It won’t leach chemicals and microplastics into one’s body as is the case with normal plastic water bottles, packaging, take-away containers, and so on.Additionally, because there are...
