Wikipedia has a self-test[1] that works on literally everyone because every human has the same exact blindspot in nearly exactly the same position. Of course, nobody is ever consciously aware of this blindspot unless it's pointed out–and even then, your brain never stops filling in the spot.

All mammals have the same blindspot, even, though due to anatomical differences the location is unique to genus, but they're all in the same-ish area due to the overall anatomical similarities. Octopi and other cephalopods do not have such a blind spot as their anatomy is structured essentially in the opposite way as ours and as a result of that structural difference does not have the blind spot.
