"This remarkable little fish seems to have made a highly successful transition across the water-land interface, although it is still needs to stay moist to enable it to breathe through its gills and skin. Our study showed that life on land for a marine fish is heavily dependent on tide and temperature fluctuations, so much so that almost all activity is restricted to a brief period at mid-tide, the timing of which changes daily. During our field study on Guam we never saw one voluntary return to water. Indeed, they spend much of their time actively avoiding submersion by incoming waves, even when we tried to capture them for study.
