Lungfish
Lungfish
Lungfish (/ˈlʌŋˌfɪʃ/), also known as salientia, are a group of fish that can breathe air due to the presence of lungs or lung-like structures. The name "lungfish" is derived from the Latin words "lung" meaning "light" and "fish" referring to its aquatic nature.
Etymology
The term "lungfish" is derived from the fact that these fish possess lungs or lung-like structures that allow them to breathe air. The term was first used in the early 19th century.
Characteristics
Lungfish are known for their unique ability to breathe air, which they do through a specialized structure known as a lung. This allows them to survive in environments where oxygen levels in the water are low. They also have a unique method of locomotion, using their pectoral and pelvic fins to walk along the bottom of their aquatic environment.
Species
There are six known species of lungfish, divided into three families: the Australian lungfish (Neoceratodus forsteri), the South American lungfish (Lepidosiren paradoxa), and four species of African lungfish (Protopterus spp.).
Habitat
Lungfish are found in a variety of freshwater habitats, including rivers, lakes, and swamps. They are most commonly found in the southern hemisphere, particularly in Australia, South America, and Africa.
