I wonder which would actually be more effective. I mean, usually fish ingest water through their mouth to pass over their gills. But that doesn't seem to be the case here. Okay, it's 1:30 am and I'm thinking of the operating principles of fictional biology. I should really go to sleep. Incidentally water maxes out at around 5% dissolved oxygen. So you'd have to move at least 4 times the volume as air, assuming the same capture rate. Water is around 800 times denser than air so you'd be moving about 3200 times thd mass.
