    I wonder if that afforded some level of protection to the surface dwellers’ receptors when in direct contact with high levels of sunlight.

      I have heard the theory that it evolved this way for higher UV protection that was not needed in underwater organisms. Curious if it was really that much of a competitive advantage though.

      As usual with biologists, if they do not understand what it does they claim it’s a useless byproduct of evolution. A few years later they discover there is actual purpose to it, and it is actually pretty nifty. Rinse and repeat.
