Because they can.
Lungfishes are a type of fish who are able to breathe on land and not just water and can survive extreme droughts. The lungfishes are harmless if certain parts are removed because they do secrete nitrigous waste and this can be considered poisonous.
Lungfishes have poor but existent lung-like organs. Actually they're air sacs but they essentially do the same job as lungs. This means that the lungfish is able to rise to the surface of the water and quickly breath in some air instead of filtering the oxygen out of a body of water where there is none.
Because they are also carrying oxygenpoor blood.
The relationship between the lungfishes and amphibians is that the lung fishes have lungs unlike amphibians who don't because they depend on water
