Two species of damselfish may look identical -- not to mention drab -- to the human eye. But that's because, in comparison to the fish, all of us are essentially colorblind. A new study published online on February 25th in Current Biology reveals that the fish can easily tell one species from another based entirely on the shape of the ultraviolet (UV) patterns on their faces.
