Semiterrestrial marine animals such as crabs and mudskippers have gill chambers in which they store water, enabling them to use the dissolved oxygen when they are on land. 14. Thus, in fish and amphibians the major respiratory muscles are cranial muscles, innervated by motor neurons with their cell bodies in the brainstem, located close to the presumed site of the central respiratory rhythm generator (RRG). a.
