Scientists have fitted a number of Praying Mantises with 3D shades. The creepy crawly clan - which contains over 2,400 species and about 430 genera in 15 families - has been given the glasses in a bid to allow scientists to study their 3D vision and explore how they use it for hunting.

According to professor of vision science at Newcastle University in England, Dr Jenny Read, the experiment could help scientists develop new ideas to use 3D technology.
"Despite their minute brains, mantises are sophisticated visual hunters which can capture prey with terrifying efficiency. We can learn a lot by studying how they perceive the world," Read said.

"3D vision has great potential in the field of robot navigation. A research associate at the university and a co-author of the study, Dr Ghaith Tarawneh said, "Robots rely on getting information from the environments. You want the robot to understand somehow its environment and perhaps move towards particular goals and it needs some sort of understanding of the environment based on visual input."
