Video of the Day: octopus sleeping and changes the color of their skin

Perhaps octopuses have dreams just like people.

Octopus - incredibly intelligent animals, and this is one more proof of that. American PBS channel posted a video with a female octopus named Heidi, who sleeps and constantly changes color.

For fifteen minutes the skin color and saturation change several times. Marine biologist from Alaska Pacific University in Anchorage David Scheel believes that this behavior is a reflection of octopus dreams. According to him, Heidi may dream as it catches crabs and wander along the seabed.

So far, scientists have not yet fully decided on, even about the nature of human dreams. Therefore, it is unlikely we will know in the near future, how the octopus dreams. However, among the animals with big brains dreams are a common occurrence, so that these strange inhabitants of the ocean, they may well be.
