There’s just one unusual detail: The diminutive cephalopod is wearing snazzy 3-D glasses.

Putting 3-D glasses on a cuttlefish is not the simplest task ever performed in the service of science.

“Some individuals will not wear them no matter how much I try,” said Trevor Wardill, a sensory neuroscientist at the University of Minnesota, who with other colleagues managed to gently lift the cephalopods from an aquarium, dab them between the eyes with a bit of glue and some Velcro and fit the creatures with blue-and-red specs.

The whimsical eyewear was part of an attempt to tell whether cuttlefish see in 3-D, using the distance between their two eyes to generate depth perception like humans do. It was inspired by research in which . The team’s results, s, suggest that, contrary to what scientists believed in the past, cuttlefish really can see in three dimensions.
