Scientists Successfully Implant Lungs into Fish

Scientists have successfully created a goldfish that is capable of breathing atmospheric air. Using advanced microsurgery techniques, researchers at the New South Wales Veterinary Institute implanted a pair of frog lungs into the fish, which survived out of water for 2 hours.

The lungs were connected to the respiratory surface that were naturally found in the gills. The fish was able to conduct gas exchange through the lungs instead of the gills, which allowed it to breath in a terrestrial environment. A very humid chamber was constructed for the goldfish so that it did not dehydrate.
