Lungfish — Only fish that HIBERNATES !

★ Lungfish can survive in very little and even without water.
★ The South American lungfish do this by digging a hole in the bottom mud where they build a nest in which they remain until water levels raises again.

★ The African lungfish have taken this a step further and covers their body with a secretion. 

★ This secretion dries to a leathery cocoon that helps the lungfish to survive until the water returns. 

★ The lungfishes remain dormant until the water returns and they will lower their metabolism during the hibernation period which allows them to consume very little to survive. They can survive up to two years in this way.

★ Having developed lungs, it is also 1 of the fish that can breathe below water as well as above water ;O
