In the PBS documentary Octopus: Making Contact, we have the opportunity to witness an incredible phenomenon!
“So here she’s asleep, she sees a crab and her color starts to change a little bit. Then she turns all dark. Octopuses will do that when they leave the bottom. This is a camouflage, like she’s just subdued a crab and now she’s going to sit there and eat it and she doesn’t want anyone to notice her. …This really is fascinating. But yeah, if she’s dreaming that’s the dream.“– Dr. David Scheel
In the video below, you’ll see a sleeping octopus begin to change colors during a dream, while she was laying upside down in the water.
Dr. David Scheel playfully narrates, and the video is nothing short of amazing!
