After leaving the land the gill lid closes tightly and the atmosphere filled with highly vascularized chamber behind the gills. Oxygen is gradually released into the body through the blood vessels (the exchange of gas). In this way, released only 50% of the needed oxygen. The rest is assumed to be the surface of the skin and fins heavily vascularized and back of the throat. Mudskipper very smoothly moves across the land - it is, jumps, and even climbs.
