The beautiful human eye:
Like a poker player sporting aviator sunglasses, a species of squid has developed a clever way to camouflage its eyes from potential predators. In the deep ocean, the light coming from behind an approaching predator is identical to that coming from behind its prey — so an animal that can reflect this light will appear invisible.These squids are really something else. But what their eyes do in nature is what sunglasses do in the circle of human sociality. When we can't see the eyes, the soul of the other becomes invisible.
