Fixed the link. Apparently, http doesn't like parenthesis.
"Although all vertebrates have this blind spot, cephalopod eyes, which are only superficially similar, do not. In them, the optic nerve approaches the receptors from behind, so it does not create a break in the retina."
Further proof that, one day, squid and octopi will rise up and conquer us all!
Nah, the squids, maybe. Octopi just think that we are nifty.
I had a teacher who had a pet octopus named 'Miss. Grundy', for reasons unknown. About the size of a saucer, when its tentacles were spread out. The little thing was friendly
and had been taught to shake hands.
Shaking hands with an octopus feels exactly
like you would expect it to.
The Auld Grump, she would also plop through hoops....
