Octopuses can light up in different colors when they dream.
That’s according to a marine biologist who captured this octopus snoozing away in a fish tank.
The neuroprocessing abilities of cephalopods (i.e. brain with tentacles attached) like the octopus activate their color-changing cells in response to their environments.
The shift to a darker color represents the octopuses movement off the seafloor while the camouflage sequence mimics the change that happens when octopuses hide from prey.
