The only possible exceptions I can think of are fish(I imagine gills and mouth are not connected but don’t really know). I am excluding bacteria and viruses and I believe they don’t really breath(correct me if I’m wrong).

    Right, that’s what I’m saying. Not enough data to make hard claims, which is why I’m saying this statement is a bit of a stretch:

    if a dolphin needs to they can breathe thru their mouths just fine.

    As far as I can tell this has happened once ever. I’m not sure that qualifies as “just fine” when there’s more evidence that plugging a blowhole is very bad for the dolphin.
