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).

Quite a lot of people can close their nose-holes by curling up their upper lip. I’m not one of them, unfortunately.
Like, airtight seal? For swimming?
Weird.
Yep, my cousin dives like that, it’s a superpower.
I have never meet your cousin, and yet I envy him.
If we ever do get practical body modification, the second thing I’m doing is getting sealable nostrils and ears, so can swim in comfort at any reasonable depth.
The first thing, of course, is getting everything that’s just fucking broken in my body fixed. The knee I fucked up doing moguls, and is getting more gimpy the older I get; the elbow I messed up trying to parkour down some stairs; my chronically fucked up back, thanks Army!
