Amazing Lungish, Who Survive on Land without Water

The lungfish, also known as “salamanderfish”, is a type of freshwater fish actually famous for its ability to live on land, without water, for months on end, and sometimes even years. The lungfish name suggests, the fish have a highly evolved respiratory system that can take oxygen straight from the air, similar of land animals do. However, few species of lungfish are quite used to breathing air that they gradually lose the function of their gills as the fish reach adulthood. Whereas they still live in water, and their requisite to frequently come up to the surface for fresh air. 

The lungfish can even drown if they are keeping him for underwater for a long time. It has elongated bodies, just like eels, with thread-like pectoral and pelvic fins which they use to swim and crawl along the bottom. The lungfish usually inhabit shallow waters, such as swamps and marshes, but they’re also found in bigger lakes. Lungfish is feeding on fish, insects, crustaceans, worms, molluscs, amphibians and plant matter. They have an intestinal spiral valve rather than a true stomach. Normally, lungfish excrete nitrogenous waste as ammonia directly into the water. The lungfish can be extremely long-lived.
