    As if cuttlefish weren’t cute enough, a University of Minnesota (UMN) research team recently equipped 11 of them with specialized 3D glasses for use in an underwater theater built just for them. The researchers did this not just so the mollusks could enjoy the viewing experience; the team wanted to investigate how cuttlefish determine the distance from which to strike moving prey. The research ultimately revealed that the mollusks use stereopsis — stereo or binocular vision — to perceive depth when hunting a moving target.
