Why did scientists put 3D glasses on a sepia?

Do marine animals have the same visual perception as people? Do not miss the results of this experiment.

Science is what can leave us perplexed with your experiments to get a truth in any field. Especially the last test that experts have done: put a 3D glasses to a sepia.

It may be a joke to observe this peculiar animal with three-dimensional glasses, but it actually has its scientific explanation after the experiment carried out at the Marine Biology Laboratory of Woods Hole, Massachusetts (USA), by scientists Trevor Wardill and Paloma González.

A vision identical to the human being
The objective of this experiment is to demonstrate whether invertebrate animals had developed stereopsis. That is, the ability of human beings to perceive depth and, therefore, to calculate distance from the obstacles we visualize.

To verify this, they used three-dimensional glasses and the projection of shrimp to study the reaction that the sepias had when viewing them.

Why was this experiment used with an animal such as sepia? The answer is in the location of your eyes. They are animals that have eyes on the front of the head, unlike other cephalopods such as squid and octopus.

Finally, this study confirmed that these animals use the eyes in the same way as humans. That is, they are able to adjust the distances to any obstacle or dam.

According to one of the researchers: «we put on our glasses and saw that the sepias were placed much further from the

Invertebrates as a research center
It is not the first time that invertebrate beings are used as the starting point of an investigation.

For example, the praying mantis have already passed the same test as the sepias and it was discovered that they were among the few insects that perceive the elements in three dimensions just like people.

It has also been confirmed that there are invertebrates that share a high percentage of our DNA. This would be the case of the fly that has more than 70% of its DNA similar to that of humans.
