Question

when do lungfishes make use of their lungs

Answer 1

During this period of estivation, they breathe air through vents into their "cocoons". In the rainy season when they become free living again, they continue to rely on lungs rather than gills as a primary means of respiration. The lung in lungfish does not have a muscular diaphragm to move air in and out.
