The South American lungfish (Lepidosiren paradoxa), also known as the American mud-fish [6] and scaly salamanderfish, [7] is the single species of lungfish found in swamps and slow-moving waters of the Amazon, Paraguay, and lower Paraná River basins in South America. [8]
South American lungfish. The South American lungfish, Lepidosiren paradoxa, is the single species of lungfish found in swamps and slow-moving waters of the Amazon, Paraguay, and lower Paraná River basins in South America. Notable as an obligate air-breather, it is the sole member of its family native to the Americas.
The South American lungfish reaches up to about 4 feet (1.25 meters) long. While other fish rely upon gills to breathe, lungfish also possess a pair of lung-like organs.
All members of the order are obligatory air-breathers; only the Australian lungfish has functioning gills when adult; members of the Lepidosirenidae have gills only when they are larvae. [5] The South American and African lungfish also all have generally small scales and two lungs as opposed to the Australian lungfish's single lung. [5]
