What manchot, pingouin species have toi seen?

There are 17 species of manchot, pingouin (although this number is disputed -- some scientists claim up to 20). What species of manchot, pingouin have toi seen at zoos and aquariums? (If toi have never seen any, say that toi haven’t and tell which ones toi would like to see.)

I have seen four species: African, Gentoo, Macaroni, and King.
