A Puzzling Riddle - What am I?

Tweet

I ran across the puzzle below earlier today while I was surfing the Internet and I thought I'd share it with you. I live, yet do not breathe. I am freezing. I am never thirsty, but always drink. What am I? Now, the answer, of course, is a Fish! BUT, there are several complaints about this question and its answer. 1) Fish do actually breathe; they just do it underwater by extracting oxygen from the water as they pass it over their gills. 2) Some fish do actually breathe air just like humans! The Arapima arapaima, pirarucu, or paiche (Arapaima gigas) is just one example. It must come to the surface every 15 minutes or so to breathe, else it will indeed drown! 3) Fish are indeed cold blooded, but they aren't exactly freezing. Perhaps compared to warm blooded animals, but still not really freezing. 4) Although fish probably are never thirsty, since water is all around them all the time and their food provides all the water they need, they really don't drink. The water they take in through their mouths is passed out again over their gills and is not swallowed. And before you can call something drinking, ya gotta swallow, don't ya?? Now you can all call me a spoil-sport, nit picky, getting all technical, or picayune! But I do feel better getting that off my chest. :-) What do YOU all think? And have you come across puzzles that weren't quite fair?
