Then they fastened 3D glasses, with one red and one blue filtered lens, to the Velcro on the skin. "It took a lot of coaxing of the cuttlefish to make them wear their glasses," Wardill said. The researchers successfully demonstrated that, like humans, cuttlefish brains can compute distance using incoming information from both eyes at once. The 3D glasses study builds on a similar study on praying mantisesBut wait: How in the world do you even get the idea to Velcro 3D glasses to mollusks? Wearing the world's tiniest 3D glasses, the praying mantises looked like six-legged movie stars , and the results gained attention for their applications to the field of robotics.
