Lungfish are freshwater vertebrates belonging to the class Dipnoi. [1] Lungfish are best known for retaining ancestral characteristics within the Osteichthyes, including the ability to breathe air, and ancestral structures within Sarcopterygii, including the presence of lobed

Imagine a fish that can breathe air and survive out of water! That's the incredible lungfish, a rare and ancient group that defies expectations. Found in the Southern Hemisphere's freshwater habitats, these "primitive" fish boast a unique biology that allows them to thrive in both aquatic and semiaquatic environments.

Feb 9, 2017 · The lungfish, also known as salamanderfish, is a type of freshwater fish best known for its ability to live on land, without water, for months on end, and sometimes even years. As its name suggest, the lungfish have a highly evolved respiratory system that can take oxygen straight from the air, just like land animals do.

Lungfish are members of the order Dipnoi. They are a sister group to the coelacanths and to the early lobe-finned fish which gave rise to the tetrapods. All these fish have paired appendages, fins or limbs, attached to a pelvis or shoulder by means of a single bone, the femur or humerus. [1]
