Lungfishes are the only group of fish that have both lungs and gills during their adult lives. Sharks, skates, and rays only have gills, lancelets only have pharyngeal gills, amphibians have lungs as adults but may also have gills during their larval stage, and ichthyosaurs and plesiosaurs are extinct marine reptiles that breathed using lungs only.
