What पेंगुइन species have आप seen?

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

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