Mudskipper

Mud-skippers are completely amphibious fish, a fish that can use their pectoral fins to walk on land. Being amphibious, they are uniquely adapted to intertidal  habitats. Compared with fully aquatic gobies, these fish present a range of peculiar behavioural and physiological adaptations to an amphibious lifestyle.

These adaptations that allow them to move effectively on land as well as in the water. The ability to breathe through their skin and the lining of their mouth  and throat . This is only possible when the mudskipper is wet, so the mudskipper s required to keep themselves dry.This mode of breathing, similar to that of the amphibians. Another important adaptation that aids breathing while out of water are their enlarged gill chambers, where they retain a bubble of air. These large gill chambers close tightly when the fish is above water, keeping the gills moist, and allowing them to function.
