This cuttlefish has its 3D glasses strapped on with the help of glue that eventually falls off. When the cuttlefish watched the shrimp dancing on the screen, they would alter their attack depending on how far away they thought the shrimp were.
#FINDING NEMO FISH WITH GLASSES MOVIE#
The 3D glasses humans use in movie theatres allow each eye to see a slightly different version of the film.īy putting the glasses on cuttlefish, researchers were able to determine whether or not the fish have stereovision, like humans, meaning each eye sees a different picture and the brain puts the pieces together in three dimensions. The Velcro was used to attach the 3D glasses. So Wardill and other researchers at the University of Minnesota conducted this bizarre experiment to study how the cuttlefish measure distance.Ī cuttle fish stares at a screen with a piece of Velcro on its head. Researchers hoped to understand how they huntĬuttlefish are in the animal group cephalopods, which means they have eight arms and tentacles with suckers attached at the ends to catch moving prey.Īccording to Wardill, what makes cuttlefish masters at snagging their meals - usually shrimp, crabs or worms - is their depth perception.ĭepth perception measures a creature’s ability to see the world in three dimensions and judge the distances between objects. They were watching flicks starring one of their favourite snacks: shrimp.Ĭuttlefish live in many oceans around the world, but are common off the coast of Europe. Researchers wanted to know how cuttlefish, which belong to the same family as octopus and squid, catch their prey, so they created an underwater theatre to study them.Īnd, no, they weren’t watching Finding Nemo or The Little Mermaid. “It was very tricky to convince them to wear the glasses,” said biologist Trevor Wardill, from the University of Minnesota. Equipped with 3D glasses and 3D movies, a group of sea creatures was encouraged to pay a visit to an underwater movie theatre, recently.ĭespite the perks, the critters were a bit resistant.
