Testing for 3D Vision in Cuttlefish

Though octopuses and squids are not capable of seeing in 3D, cuttlefish do boast depth-perception, recent research studies at the University of Minnesota confirmed. When donning 3D glasses, the cuttlefish could not only detect a shrimp (which comprised of projected images in two different colors and at two different distances), but also actively position itself for an attack. After identifying the shrimp, the fish backed …
