Cuttlefish have the ability to watch 3D movies and react to them much like they would if they saw the real thing out in the ocean.

And when it comes to depth perception, they’re incredibly proficient.

Those are the findings from a study published Wednesday in the journal Science Advances.

Trevor Wardill, an assistant professor of ecology, evolution and behavior at the University of Minnesota and lead author of the paper, told CNN his team super glued Velcro to the skin of the cuttlefish. Then they fastened 3D glasses, with one red and one blue filtered lens, to the Velcro on the skin.
 
 On a screen at the front of the cuttlefish tank, the researchers played video of shrimp, one of the species’ favorite tasty snacks.

“It took a lot of coaxing of the cuttlefish to make them wear their glasses,” Wardill said. “They’ll want to play with it.”

But when the little critters behaved, something magical happened.
