| The Globe Fish lives in shallow water and uses its swim bladder to ascend and decend in the water. The swim bladder is a sac inside the abdomen that contains gas. If you have caught a fish and wondered why its eyes are bulging from its head, it is because the air in the swim bladder has expanded and is pushing against the back of its eye. The gas in the swim bladder is mostly oxygen. Nitrogen and carbon dioxide are also present. De zwemblaas stelt de vis in staat om zijn massadichtheid continu aan te passen en het lichaam in de gewenste positie te houden zonder dat de vis verder energie hoeft te verbruiken met zwembewegingen.\\ | The Globe Fish lives in shallow water and uses its swim bladder to ascend and decend in the water.
