South American lungfish

The South American lungfish, scientifically known as *Lepidosiren paradoxa*, is a unique species originating from freshwater habitats in the Amazon Basin. This species is characterized by its elongated, eel-like body, which is generally a brownish or grayish color, aiding in its camouflage in the murky waters it inhabits. The South American lungfish possesses both gills and a primitive lung, allowing it to breathe air in oxygen-depleted water. While it has a certain appeal due to its unusual appearance and fascinating biology, it is not among the most common species kept in the aquarium hobby. This is partly due to its large size, reaching lengths of up to 125 cm (nearly 50 inches), and specific care requirements.
