don't forget the aardvark, nuncle.

Different animal, different languages, same name. The Afrikaans vark is related to German Ferkel 'suckling pig' and Latin porcus. And off the West Coast of Eire, there's some little islands, one of which is Inishshark. It has little to do with sharks, but with MIr orc 'pig', cognate with the others above. I was on Inishbofin 'isle of the white cow' once. A lovely place.
