What 펭귄 species have 당신 seen?

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

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