Praying Mantises Have 3D Vision, New Research Revealed

Praying mantises have 3D vision..! Praying mantises can’t discern the world as human can do, while they are also not so clever, as they are insects.

A team of researchers performed an experiment on praying mantises by dressing their eyes with 3-D glasses, which later discovered a unique type of stereo vision. The discovery has been published in the journal Current Biology, which helps scientists add improvement in the sights of robots.


A fellow researcher and Vision Science professor, Jenny Read from the Institute of Neuroscience at Newcastle University said in a statement that, “Current machine stereo algorithms require a lot of computing power. Reducing the amount of computer power necessary means smaller, lightweight robots could use mantis stereo algorithms to detect depth.”

Using two light filtering lenses with teardrop shape settled on the heads of praying mantises, scientists provoked the insects to suffer lab experiments at pictures of enticing pray in effective 3D film, the research team said.

There are 85 billion neurons present in the human brain; however insects like praying mantises have less than a million numbers of neurons. Despite the neuronal drought of the insects, mantises have conceived a new invention of seeing in three dimensions.

Vivek Nityananda from Newcastle University, one of the leading authors of the study stated that, “Mantises only attack moving prey, so their 3-D doesn’t need to work in still images. We found mantises don’t bother about the details of the picture, but just look for places where the picture is changing.”
