    It seems that cephs are not the only ones who may use light as a communications method. The month's Practical Fish Keeping has an article that reports potential use of red light by fish to communicate.

    This is not that surprising. Many organisms fluoresce in the red. There are several stomatopods that live below 30 m that flouresce in the red as do many coralline algae, sponges, and corals.

    Roy,
    Does that mean that fish "not seeing red" is now an old theory and no longer considered true or is it that red is still a unique color to the underwater spectrum but that numerous fish/inverts utilize its absence to communicate?

    This is my favorite paper from the "blue is the norm, red is the exception" camp:

    http://www.ncbi.nlm.nih.gov/pubmed/15366767

    Unfortunately, that's just the abstract. I am a believer that fair use allows redistribution of the PDF for nonprofit educational purposes, however. :read:
