On the last dive I made I saw a dead northern that had the tail of another fish sticking out of it's mouth. My first thought was that it must have choked to death on the fish. After think about it for a while this seems unlikely. I don't know much about fish anatomy but I don't believe they have 'airway' to that could get blocked. I'm assuming the gills transfer the oxygen directly into the blood stream.
If decided that it was more likely that the fish probably starved to death. What do others think? Can someone enlighten me on how a fishes gills work?
