Cuttlefish in 3D Glasses

Cuttlefish look pretty weird. They’ve got eight tentacles coming out of their face, a flat, flowy body, and two enormous eyes that, like our eyes, work together to see the world in 3D. Scientists discovered that last part by velcroing 3D glasses to the faces of cuttlefish and showing them movies. But why do we need to know if cuttlefish see in 3D? University of Minnesota ecologist Trevor Wardill explains. (Originally aired February 4th, 2020)
