The characteristic that makes marine mammals different from other marine animals is that **they breathe air through lungs**. Unlike many marine animals that can extract oxygen from water through gills, marine mammals must come to the surface to breathe air, as they are warm-blooded and have lungs. This distinguishes them from fish and other aquatic creatures.
