The lead author of the study, Ringvold, explained in an interview life sciences Investigation process: “We can see what is inside the real sphere. The squid embryo is in four different stages (…). In addition, we can track how the sphere works Consistency of changeAs the embryo develops, it goes from hard and transparent to brittle and opaque,” he said.
This kind squid, Belong to this family mm sectionInhabits the Mediterranean and North Atlantic.During reproduction, the females of this group produce Big egg ball made with own slime Ringvold said to keep their embryos floating and protected from potential predators.
Although this species has been known for more than 180 years, Witness Their egg bag is Quite rare Until now, they have never been discovered.
