Lungfish is the generic name given to a group of fish belonging to the families Ceratodontidae, Lepidosirenidae and Protopteridae. Each family represents a different continent where they can be found specifically, Australia, South America, and Africa.
Lungfish get their name from the fact that they can breed atmospheric oxygen by using lungs similar to those found in early amphibians. This adaptation allows them to survive out of the water and in waters with very low oxygen content.
All lungfish are freshwater fish that belong to the subclass Dipnoi, and all have modified swim bladders or “lungs” that allow them to absorb oxygen and remove wastes.
The African and South American species all have two lungs and are able to burrow into the mud and secrete a mucous lined burrow where they can survive out of water for quite some time. They are able to dramatically reduce their metabolic rate and breathe air through their swim bladder instead of their gills. If kept underwater, these lungfish will actually drown if they are not able to surface for a gulp of air.
The Australian lungfish (Neoceratodus forsteri) is the largest, most primitive species, and has only one lung. Unlike their African and South American counterparts, they can survive out of water for prolonged periods if they are kept moist. Although they can breathe air using their “lungs” when out of the water, they cannot survive complete desiccation like their African and South American cousins.
Neoceratodus forsteri is native to the Mary and Burnett River systems in Western Australia and is protected under CITES. It is rarely seen in the aquarium hobby by tropical fish keeping enthusiasts.
The African and South American lungfish have adapted to survival when the pools of water that they normally live in evaporate during the dry seasons. They are able to burrow into the mud and seal themselves into a mucous lined capsule or burrow, until the rainy season restores their natural habitat.
