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.

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

Wonder what would happen if an octopus looked directly at the sun

As usual with biologists, if they don’t 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’s actually pretty nifty. Rinse and repeat.
