Are there any fish whose lungs and cheeks breathe at the same time?
Yes
Fish's lungs are well developed and can be used frequently. Therefore, it is not a problem for amphibians to breathe in the air, but to continue to use the lungs inherited from the ancestors of fleshfin fish. The main difference between fish and amphibians in this respect is that most fish with lungs still breathe through gills. The lungs are usually only an auxiliary respiratory organ, but the earliest terrestrial vertebrates basically breathe air through the lungs and only breathe through gills in their infancy or larval stage.
