Their gills, and their respiratory system. :)
Fish can live and move in water thanks to fins that allow them to swim, gills that help them breathe, and a swim bladder. The swim bladder keeps fish buoyant in the water.
The main features of most fish are that they are cold blooded, live in water, their bodies are covered in scales, they have gills, and fins. Some fish also have big eyes, or whiskers.
