New York: An octopus in an aquarium surprisingly, in deep sleep, suddenly began to fight as if attacked by an enemy. Scientists have concluded that octopuses also have nightmares.
Eric Ramos, a neuroscientist at the Rockefeller University, walked into his lab one morning to find an octopus in his aquarium. They noticed that the water in the aquarium where the octopus was, was cloudy and full of ink. Ramos was surprised to see this.
Ramos’ surprise was that when the octopus secretes ink, it is a defense mechanism it uses to avoid predators, but there were no predators in the octopus’s aquarium and it was in a deep sleep. was
To find answers, Ramos checked the video recordings recorded throughout the night. It can be seen in the video that at first the octopus was sleeping peacefully. But suddenly, without any provocation, he started exhibiting agitated behavior, changed skin color, started jerking here and there, increased body size and secreted ink. Threatened by hunters. And adopting this attitude while sleeping shows that the octopus was being attacked in the dream.
