The mantises were then shuffled into a “3D insect cinema” and shown computer-generated images of different targets moving toward them. The results will help scientists get a better understanding in how 3D vision evolved!
“Dyed snail excremental that have been altered by a diet of colored paper. The snails are fed a strict regime of colored cellulose paper and because they cannot assimilate the paper’s pigments, their bodies reject the color of the ingested paper creating colored excitements. Applications include floor tiles and can be used for packaging.” (at Material ConneXion)
