Evolutionists often try to use fish that can live out of water to support various theories of the origins of living things. One example is a family of fish known as mudskippers (Oxudercinae).

Mudskippers can live as long as 2 ½ days out of water. They live along the shorelines in tidal pools where there is very little oxygen. They burrow into the mud when the tide goes out and stay there until the next incoming tide. Mudskippers inflate their mouth and the cavity around their gills with air. When the fish emerges from the mud, it deflates and immediately takes another gulp of air. Their mud burrows contain enough oxygen for the fish and its eggs to survive. This is a case where the fish modifies its environment to survive in a place where life would otherwise be impossible.

In Michigan, we have a fish called the bowfin (Amia calva) or popularly called dogfish. This species of fish shows up in some of the earliest rocks of the Earth. They have obviously been around for a long time, so sometimes they are called “living fossils.” In addition to gills, they have gas bladders with a small pneumatic duct that allows them to gulp air and survive for some time out of water.

Do these fish that can live out of water show a transition between aquatic and land animals? The short answer is “no.” They do show that living things were designed to adapt to changing environments and even to modify their environments for survival. The more science researches living things, the more we realize that God has designed animals and plants to make every ecosystem alive with life. It is up to us to take care of the environment as we marvel at God’s creative power and wisdom.
