    Squid skin and ceph adaptive coloration have become an on going news item since the military (navy) has shown interest in learning the secrets of ceph camouflage. Use this topic to collect the latest articles uncovered.

    Here is a list of papers on the topic from the Woods Hole Research Library

    NON-ceph Lizard “Sees” With Its Skin For Automatic Camouflage

    I have often wondered if ceph skin has evolved to do something similar (and more efficiently) since their eyes cannot see color. Are there studies that have blinded cuttles or octopuses to see if they still color change?

    Wow- amazing article on lizards! So incredible! Cephalopods have opsins in the skin that are mentioned to possibly offer some degree of light sensing ability but the degree to which this actually helps camouflage (I think) is unknown.

    Nice to know that there are similar physical properties. Maybe this study will encourage (or expose one already done) ceph experimentation. I remember @robyn creating a blindfold of sorts for squid for one of her pain experiments (I don't think it totally removed sight though - sadly the blogs did not survive the softward upgrade so I can't find the images or post) but coming up with something for octopuses or cuttles that does not involve permanent blinding would be difficult.

    Cuttlefish adjust body pattern intensity with respect to substrate intensity to aid camouflage, but do not camouflage in extremely low light Kendra C. Buresch, Kimberly M. Ulmer , Derya Akkaynak, Justine J. Allen , Lydia M. Mäthger, Mario Nakamura, Roger T. Hanlon 2014 (subscription)

    Skimming reddit today and saw this:http://www.theguardian.com/science/neurophilosophy/2015/may/20/octopus-skin-contains-light-sensors

    It links to this journal article:
    http://jeb.biologists.org/content/218/10/1513.abstract

    I have downloaded the file for those to get around the paywall. But because i don't want to seem like i am a virus-peddler i have uploaded image versions of the pdf to imgur. You can view it here: http://imgur.com/a/cWSbn

    If you want the pdf i have uploaded it here: http://dropcanvas.com/bf79r

    (images and pdf both include supplemental material)

    What do you guys think? I am not a biologist so a lot of this paper went over my head, but it seems very interesting. Is this how they camouflage themselves so well?

    Thanks for the links! :thumbsup:

    Incredible story, isn't it? Aliens on earth.

    As a side note, I will soon overhaul our "news" features - we'll need to start providing curated Top Stories again, as we used to.
