PBS has released a documentary that shows some fascinating details about octopuses. It’s called Octopus: Making Contact and it’s been created in collaboration with Dr. David Scheel, a professor of marine biology at Alaska Pacific University.
Dr. Scheel kept the octopus from the film in captivity for a long time, closely studying its behavior. That’s why he’s able to explain one of the most fascinating parts from the documentary which you can see below. In the Youtube video below, you can see the octopus changing colors as she sleeps, for which Dr. Scheel says it’s the result of dreaming about hunting.
“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,” Laughing Squid quoted the professor.
