Have you ever seen your animals sleeping? When their feet and beard are shaking and moaning and trembling? Well, cats and dogs have REM sleep, which may indicate a dream. But have you ever seen an octopus sleeping before? Here’s a video of Heidi changing her color to look like an owl’s dream. Furthermore, there is no evidence of REM sleep in octopuses to date, and they have their sleep pattern. Octopus usually light up when they are asleep. When they are at rest, the neurons in optics activate the chromosomes or cells that retain pigment due to fire. As a result, the sermons move between colors and patterns at bedtime, reacting only to their feelings.
Siddhartha Ribeiro and his colleagues have confirmed that the octopus is in two stages of sleep from the Federal University of Rio Grande do Nort in Natal, Brazil.
Scientists videotaped four common octopuses in the laboratory (Octopus Vulgaris) for more than 180 hours, day and night. Ribeiro says the animals slept for more than half a day. “They stayed in the same place for a long time, and the students were closed, very quiet, very pale – they were quiet, quiet, regular,” he said. This restless sleep was interrupted by a short active sleep of 1 to 2 minutes every 30-40 minutes. Throughout this period, the octopus revealed changes in body type and texture, including the appearance of fine lumps on the skin called papilloma. The eyes and hands of the creatures also moved. “It’s very busy,” Ribeiro says.
By showing them a tape of several crabs, the team assessed whether the octopus was asleep. In stark contrast to your statement, Ribeiro said: ‘If we stimulate the animal with visual or perceptual stimuli, they do not react. ‘Heidi goes from beautiful white to dark purple to violet before the hiding elements become a complete design. But Heidi isn’t the only octopus filmed in color-changing sleep. The sleeping Caribbean double point octopus in October 2017 was filmed by Rebecca Otti, who was involved in the Invertebrate Exhibition at the Butterfly Pavilion.
