In the viral video, the octopus sleeps in the black, along the top of the water, suctioned to her tank’s glass walls. Her reflection is slow ripples. At first she’s a placated white, like pristine glaciers that have avoided pollution. The texture roughens—spiky as the fragile coral reef that breathes brown, yellow, and gray. When head twitches, she clouds into the red, purple, and black until transitioning to a gray that surrenders to yellow. Her head and eyes waver but remain shut. Somewhere in its dance of color, I saw a martian landscape appear, a cloud of harsh storm, and then back to the peaceful swivel and drift of clouds that bounces on the water’s surface. The scientists report it unlikely to be octopus dreams, but instead of worrying, I accept all invitations to be submerged.
