Lungfish are freshwater vertebrates with the ability to breathe air. They have lobed fins and a well-developed internal skeleton. The African Lungfish can live for many months in mud burrows without water. In certain parts of the world where they are abundant, the locals eat them as a ready and rich source of protein.

The lungfish hibernates at the bottom of the ocean. And can breathe through its gills only for up to five years. On land or in mud, it can survive for 3-4 years, breathing air through the lungs. Six documented species of lungfish can live for 20-25 years.

The fish adapts by burrowing in the mud to create a safe habitat where they survive for long periods of dormancy.
