Scientists put 3D glasses on cuttlefish -- and discovered remarkable things about how they see the world
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.
The researchers successfully demonstrated that, like humans, cuttlefish brains can compute distance using incoming information from both eyes at once. However, they write in the paper,"Cuttlefish stereopsis is likely afforded by a different algorithm than in humans, and not just a different implementation.""We don't know the neural basis," Wardill said."That's not an easy task to do.
