Then the tail becomes smaller and smaller until it is removed. The formation of the mouth is very important to an amphibian. During the development of the mouth and jaw, the animal is unable to feed. In preparation for this phase, large quantities of foods are stored. Metamorphosis is a fascinating transformation, providing scientists with a greater understanding of the biochemical and physiological processes.
Most amphibians avoid daytime temperatures and low humidity.
During the day, they usually stay in areas with high moisture content, and they stay in insulated areas away from air currents. Inside a log and in mounds of soils serve as good places to spend the day. Amphibians may come out during the day, but only if there is a sufficient amount of moisture. However, they might risk water loss or even death to accomplish some goal such as feeding or mating. Amphibians can reduce water loss by reducing the amount of surface area exposed to evaporation.
