TIME TO CATCH
          YOUR BREATH
          A male tree frog may croak 100 times
          per minute for hours on end in order
          to attract a female, and that requires
          a lot of energy. Some of them can
          croak at volumes above 100 decibels,
          which is about as loud as a chainsaw.
          Frogs are assisted in their powerful
          sound production by a larynx that is
          almost a quarter of an inch wide—
          about one-fifth of their body length.
