       | Cuttlefish are fascinating. From Wikipedia [0]:
       | 
       | "Cuttlefish are able to rapidly change the color of their skin to
       | match their surroundings and create chromatically complex
       | patterns, despite their inability to perceive color, through some
       | mechanism which is not completely understood. They have been seen
       | to have the ability to assess their surroundings and match the
       | color, contrast and texture of the substrate even in nearly total
       | darkness."

         | if they only have one kind of receptors on their retina. This
         | is thanks to very oddly shaped pupils which focus different
         | wavelenghts in different parts of the retina.

       | Something I have always wondered about articles on research
       | papers. Is it the norm or standard that they always consult and
       | expert in the same field that wasn't part of the research? why is
       | this?
       | 
       | I have seen this in many physics articles too. I am not against
       | it as it seems purposeful.

       | Some books I cannot help but recommend:
       | 
       | Non-Fiction:
       | 
       | - Sy Montgomery: _The Soul of an Octopus_
       | 
       | - Peter Godfrey-Smith: _Other Minds_
       | 
       | Fiction:
       | 
       | - Shelby Van Pelt: _Remarkably Bright Creatures_
       | 
       | - Ray Naylor: _The Mountain in the Sea_
       | 
       | They are each fantastic, and anyone curious or a fan of
       | cephalopods should read 'em.
