There are three terms we need to define: Holland, the Netherlands, and Dutch. In Old English dutch simply meant “people or nation.” (This also explains why Germany is called Deutschland in German.) Over time, English-speaking people used the word Dutch to describe people from both the Netherlands and Germany.
Most frogs and toads breathe (and take in moisture) through their skin through a process called cutaneous gas exchange, but they also have lungs with which they breathe. During the time they stay submerged under water or buried in soil (such as during hibernation) they ONLY breathe through their skin.
