Explanation

When you go on a nature walk in a school setting, your teacher might tell you to observe the flora and fauna in the woods. Flora is plant life; fauna refers to animals. Fauna derives from the name of a Roman goddess, but the handiest way to remember the difference between flora and fauna is that flora sounds like flowers, which are part of the plant world; fauna, however, sounds like "fawn," and fawns are part of the animal kingdom.
