Can creatures of the sea see in 3D? Cuttlefish were equiped with 3D glasses to test their vision [cracked.com] with surprising results. Not only can they see in 3D, they look adorable doing so. By equipping them with glasses [youtube.com] (warning: Youtube link) scientists were able to test for depth perception.
