A 10 second movie that captures the exact moment of the birth of a Caribbean octopus on the cliff (Octopus briareus) is having a viral success on social media (on Facebook it has been seen over 2.4 million times).
Color change. The video made by the marine biologists of the Virginia Aquarium shows a baby cephalopod coming out of its own egg, placed next to those of the "brothers", in a structure that resembles that of a flower. The small initially transparent, almost immediately takes on a brown color, while it unfolds the mini tentacles and begins to swim.
For researchers who have witnessed the happy event, the change in tone is due to the stress of birth or to a strong and innate instinct for mimicry (which in the octopuses reaches the highest peaks).
Independent. In nature, the females of this octopus, typical of warm neotropical waters, can lay up to 200, 000 eggs which take about 65 days to hatch. The baby octopus at birth is 15 millimeters long and completely autonomous: since both parents generally died at the time of hatching - because they devote all their energy to conception and defense of the eggs - at birth the mini molluscs already know how to move and splash ink.
