Scientists have discovered that praying mantises use an unknown kind of view

A team of scientists under the leadership of Vivek Nityananda from Newcastle University have tried to understand the complicated nature of view Bogomolov, but got more questions than answers. Unlike other insects, mantises have eyes facing directly forward, and it would be logical to assume that they use binocular vision, as the primates. But it was not so.

To understand where to look to each eye of the mantis, the scientists attached a tiny lens-sensor with beeswax. The procedure is painless, and the use of lenses of different colors have allowed to accurately identify where to focus specific eyes. Further, the screen started to slide the point to the target, and the mantis is accurately “aimed” at her both eyes.

In the second experiment, the researchers went to the trick: point suddenly divided and two new ran in different directions. But the mantis continued to monitor the movements of both the different eyes. Turns out he didn’t need to overlay a picture from the right eye image from the left to get a depth of vision and to recognize the approaching object. The insect is oriented in a three dimensional world with one eye and this type of vision science is still unknown.

Brain mantis has only a million neurons, compared to 85 billion in humans, but this “computing power” is enough to provide three-dimensional vision with sparse source data. If scientists can understand how it works, they will be able to create “electronic eyes” to the primitive, massive robots, which are just nowhere, and expensive to put sophisticated equipment for orientation in space.
