Cuttlefish Wearing 3D Glasses Watches Film Clips, Astonishes Scientists with Rhe Results

Science

The cuttlefish can watch and sense 3D objects and react to the films just like they would after seeing it in real life. In a study conducted by a team of scientists at the University of Minnesota, the scientists glued a 3D glasses to the velcro attached to the skin of cuttlefish to observe the reaction of the animal after seeing 3D film clips. The 3D glasses had one red and one blue filtered lenses.

They placed a screen in front of the cuttlefish tank so that it could watch the film. Then the scientists played a 3D video of Shrimp, which is known as a favorite prey of the cuttlefish. The cuttlefish can also sense the depth easily. The findings from the study were published in the Science Advances journal on Wednesday. Trevor Wardill, lead author and assistant professor of ecology, evolution, and behavior at the University of Minnesota, told the sources that it was hard to make the cuttlefish wear the glasses.

As the cuttlefish saw the shrimp move on the screen, it extended its tentacles and tried to attack it. Before conducting the study, the team of Wardill visited the Marine Biological Laboratory at Woods Hole, Massachusetts. The team experimented with 11 species of cuttlefish react to the films. The eyes of cuttlefish have a cornea, lens, iris, and retina. They can discern the distances between two objects because their brains can interpret the signals received from the eyes. The cuttlefish adjusted its position while watching the screen as it would do in real life. It has a better ability to perceive depth. In the paper, the team of Wardill concluded that the cuttlefish could comprehend the distance between two objects using the information it receives with two eyes.
