Personally, beyond identifying various fish species, I don’t care about the why’s of color beyond adaptation and camo. I simply marvel at their individual beauty. Good enough for me. My mind, anymore, glazes over with too much detail re fish, entomology, climate change, etc. I simply want the decompression and want to think less and less. For now anyway.
“Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be
satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.”
