Indeed! i went to a talk last spring about "how fish see" The presenter provided a tremendous amount of detail, scientific research, hypothesis, personal field experience -- and when he was all done, essentially indicated that in the end it was of course all speculative since none of us have ever discussed with a fish what they see nor have we actually seen the world as a fish.
I will skip the story about the very attractive Lady i once saw, dressed elegantly, carrying herself with perfect deportment walking down the street with her companions ..... until she spotted the full moon and started howling like a banshee and carrying on like the wolf man -- of course, i guess i just told the story anyway.
Thank you very much my good friend. I am ever fascinated by the moods of nature. Contrasting wildlife that has a design meant for great disguise, and then instances like this where the bright colors shine through. It all must have a very good purpose, which we may one day clever enough to know. i love your thought on that tail -- that is spot on for a description. if we kept better track of the moons, we might keep ourselves out of a whole lot of trouble that the chronograph does not do.
