Cuttlefish aren t wearing 3D glasses to enjoy state-of-the-art movie theater technology, but rather to help scientists better understand how they see the world. It turns out that when it comes to depth perception, these little squid-like sea creatures are extremely skilled.A study published Wednesday in thejournal Science Advances suggests that, contrary to what scientists believed in the past, cuttlefish can

By fitting 3D glasses on cuttlefish, scientists discovered that the creatures use stereopsis to calculate depth for capturing prey.
