The point is how much you can see without moving your eyes.
Yeah we can technically see a pretty wide range but that’s mainly peripheral. You can’t really make out details unless you move your eyes to look directly at something.
Whereas prey animal eyes aren’t supposed to be super detail oriented in the first place. So they can see more without moving their eyes to look directly at something because details aren’t important.

okay but that has nothing to do with field of view, which is what the example is about.
It has everything to do with field of view… the region in which is you can resolve detailed information is very narrow, at only ~15º.
