Cuttlefish Use a Human-like Level of Eyesight to Help Camouflage Themselves

By Josh Saul 10 years agoNo Comments

Sarah Zylinski, a researcher at Duke, recently focused her attention on the eyesight of cuttlefish.  Through various tests, she was able to identify  the ability of cuttles to identify shapes in the same way that humans do.  Despite cuttles being colorblind, they actually have a very developed sense of sight as indicated by their ability to pick out circles in a pattern.  How do the cuttles prove that they see the object?  They use their ability to change color as a camouflaging mechanism.  Included in the great article on the study, is a link to a cool cuttlefish image gallery that you HAVE TO see.
