A flooded city of octopuses hatching eggs in front of scientists for the first time!

Ten years ago, researchers discovered something amazing. Octopus nursery. An area where female octopuses seem to congregate to hatch their eggs. a team of Schmidt Institute of the Oceans (United States) Today I discovered a new arboretum of its kind off the coast of Costa Rica, near a hydrothermal vent. All at a depth of more than 2,800 metres.

When researchers first discovered a nursery in 2013, they didn’t detect a developing embryo. So, the most amazing thing about this story is that this new expedition allowed them to take very rare photos thanks to a remote-controlled underwater vehicle. Newborn octopuses emerge from their eggs both in the newly identified incubation, but also in the old incubation they thought was inactive.

Active octopus nurseries

The researchers point out that octopus reproduction in the open sea is a long process. It happens that females incubate more than four years of eggs which they must keep clean and which they must protect. As a result, they end up sacrificing their lives for the sake of their offspring. Hydrothermal vents and their hot fluids can help speed up the development of their eggs.

By chance – or not – the expedition allowed scientists to spot thriving biodiversity on five previously unexplored seamounts. Hundreds of animals, many of which are suspected of belonging to new species. In places that are not currently protected from human activities such as fishing.
