you can drown pretty much any fish! In un oxygenated water they can't filter out any oxygen (obviously) and they drown. algae blooms do it. and apparently things like paper mills do as well if the water they use doesn't get cooled before it goes back in the water!
Also sharks drown if there isn't a flow of water through their gills, so they can't stop cruising for more than a minute or so.!!
