Uhh, not in the oddly spe—cifi-c way you suggested, but.
See, here’s the thing about gills. They are pretty much totally sealed shut if you’re on the surfa—ce. The mus—cle basi—caly shuts down, be—comes involuntary. You might get stuff on the protective frill over the —casing, but it won’t, you know, get in your gills. (You’d have to pry them open to do that, and the thought alone of that was painful. Typing that was painful. Eughhh.)
However, when you’re underwater, they open up, and be—come more —controllable. You —can open and —close them in a somewhat limited fashion however you please (closing them underwater would be part of holding your breath, basi—cally). So if you have bad timing when it —comes to holding your breath, and you’re swimming in a shallow, sandy area… You might wind up with a problem.
I’ve definitely had to deal with that dis—comfort before. Most seadwellers do it at some point when they’re really young. The worst that happens usually, though, is that you —cough it ba—ck out again. Obviously, in polluted waters or —certain dangerous kinds of debris worse things —can happen, but that goes for breathing on the surfa—ce too.
