"Content": "Document name: Lungfish\nDocument fragment: Lungfish are an ancient type of fish with unique physiological structures and survival abilities, belonging to the order Dipnoi under the subclass Sarcopterygii of the class Osteichthyes. They first appeared around 400 million years ago during the Devonian period and are one of the oldest existing fish species.\n\n\nMain features\n\n\nRespiration: Lungfish have two respiratory organs: gills and lungs. In water, they breathe mainly through gills; when the water dries up, they can use a specialized swim bladder (called a \"lung\") to breathe air directly.\n\n\nMorphology: Lungfish have a slender body, with thick and powerful pectoral and pelvic fins that allow them to walk on the bottom. Their scales are small and their body is eel-like, helping them move flexibly through dense aquatic vegetation.\n\n\nSurvival ability: Lungfish can survive in dry environments. When rivers dry up, they drill into the mud, form a cocoon-like structure, breathe through the lungs and internal nostrils, and wait for the rainy season to return.\n\n\nDistribution and types\n\n\nDistribution: Existing lungfish are mainly distributed in the freshwater environments of South America, Africa, and Australia.\n\n\nTypes: The order Dipnoi includes two main families: Lepidosirenidae and Protopteridae. Among them, the Australian lungfish, South American lungfish, and African lungfish are common types.\n\n\nLiving habits\n\n\nDiet: Lungfish feed on crustaceans, mollusks, and worms. They have a powerful bite force and can prey on shelled invertebrates.\n\n\nReproduction: Lungfish have diverse reproduction methods. Some species lay eggs in aquatic plants, and the larvae have no external gills and develop without metamorphosis; other species require metamorphosis, and the larvae\n\n\nProtection status\n\n\nDue to their unique physiological features and important scientific research value, lungfish are listed in \"Appendix I, Appendix II, and Appendix III of the Convention on International Trade in Endangered Species of Wild Fauna and Flora\" and are subject to international protection.\n"
