Researchers are studying mantises to learn about 3D vision In 1983, Samuel Rossel determined that mantises (of which the praying variety is the most famous) possess 3D vision. Piggybacking on this discovery, scientists at Newcastle University are researching how to gain a better understanding of 3D vision by taking a closer look at mantises’ vision. The team is attaching 3D glasses to mantises’ eyes to see if they will be fooled by the presence of 3D images. The researchers will attempt to compare mantises’ stereotypic vision to that of the human world and how 3D recognition has developed across various...
