True. What I'm basically talking about is the vertebrate eye, but there's that fascinating parallel evolution of the cephalopod eye (is it just squid, or do the octopus and the nautilus also have eyes amazingly similar to vertebrates' eyes?).
Unfortunately I know even less about visual processing in squid brains than I do about cat brains. We only covered anatomy, not neurology, in my 12th-grade Estuarine Biology class.
Now I'm going to have to find a raptor to observe, and a lizard with big eyes, and a squid, to see whether their pupils change size in response to motion when hunting. And some human volunteers.
I seem to recall that there's some significant difference between the vertebrate and cephalopod retinas. Cannot recall whether it was purely anatomical or neurological as well.
