Please don’t say that it could die because there isn’t enough oxygen in the air for them. Commonly, that is what people think. The fact about this myth that is wrong is, that there really is actually more oxygen in the atmosphere than in the ocean or any body of water. Fishes, in fact die from dehydration first and then suffocation. The reason for this is because fishes receive oxygen through their gills via counter-current flow. Their gills are loose and flow in water which allows them to accomplish that. When taken out of their environment, their gills close up, defeating their ability to receive oxygen since they lack lungs. It’s like when you wear regular clothes and dive into the swimming pool—they float around in the water. The instant you get out, however, they cling to you like glue; a feeling that I find the most unpleasant.
