Apr 14, 2017 at 21:09 comment added AliceD In terms of the number of photoreceptors; that may only benefit light sensitivity and not visual acuity dependent on the connections with the secondary neurons. The blind spot in humans is mitigated by binocular vision.
Apr 21, 2014 at 20:59 comment added Superbest Would the blind spot matter? The respective blind spots of the two eyes don't overlap, so unless you are a pirate (I suppose a frequent victim of sharks), you will still see all the things in either of your blind spots, there will just be two small spots in your FOV where you don't have depth perception.

But In some manner of course the Octopus will see the Shark first because they didn't have blind spot so their field of view is more than a common person.

Jan 7, 2013 at 19:01 comment added Nathaniel Bubis So if a diver and an octopus where to be threatened by a shark, the octopus would see the shark first?
