Description

The South American lungfish is an ancient freshwater fish of the family Lepidosirenidae, the only lungfish of South America. The species grows to about 1.25 metres and has an elongate, eel-like body with thread-like, greatly reduced pectoral and pelvic fins. It prefers stagnant waters with little current, such as swamps and floodplains. Notably it breathes air with a pair of true lungs and must come to the surface; in the dry season it can burrow into a moist mud cavity and survive in dormancy (aestivation). Juveniles eat insect larvae and snails, adults also plant matter. The species is harmless to humans.
