We all have our blind spots — or do we??
The layout of human eyes and cephalopod eyes is remarkably similar, but in humans, the nerves that carry visual signals to our brains run across the front of the retina, while in cephalopods, those same optic nerves run behind the retina. Where those nerves exit our eyes it creates a blind spot, because there’s no room for photoreceptors to sense light that strikes it there. But cephalopods don’t have that problem since their nerves run behind the retina! Inkredible, right?!
