Researchers put 3D glasses on cuttlefish for...science

It may seem like that cuttlefish is prepping to see The Rise of Skywalker but no, it's actually part of a research experiment.

A team at the University of Minnesota put 3D glasses on cuttlefish in order to learn more about their eyes and brains, specifically how both organs work together to catch prey. Like humans, cuttlefish utilize stereopsis, the scientific term for depth perception. Unlike humans, cuttlefish still hunt their prey — and stereopsis helps them do it. The cuttlefish strikes at its prey and must correctly guess how far away it is. If it's too close when it strikes, the prey will get spooked and move away; too far away, and it won't reach.
