VIDEO SI. This is an amphibious airbreathing fish, the giant mudskipper Periopthalmodon schlosseri. It uses its buccal cavity as an air-breathing organ, it holds air in its mouth which, at intervals, it exhales and replaces with a fresh mouthful. All airbreathing fishes retain their gills, when the mudskipper exhales, you can see it takes three gill ventilation cycles with water before gulping air.
