FIREFLY, "Perfect Light"!..

If you have touched an electric light bulb that has been on for a while, you will know that it can get very hot. The heat produced by the bulb results from wasted energy. Atypical light bulb gives off only 10 percent of its energy as light, while 90 percent of its energy as heat. In comparison, the tiny light producing insect called the firefly is nearly 100 percent efficient.
Fireflies waste so little energy as heat that the light they produce has been term "perfect light". How do they do it? The abdomen of a fie fly contains an organic substance known as luciferin. When oxygen is drawn into the abdomen through a tube called the abdominal trachea,it mixes with luciferin, and the resulting chemical reaction gives off a pale-yellow to reddish-green glow.
The cell that produce the firefly's light also contain uric-acid crystals, which help to reflect the light away from the insect's abdomen. Scientists say that the fireflies use their light to attract mates and that different species of fireflies flash different patterns and rhythms.
Would you not agree that the way in which these tiny but wonderful creatures are made gives praise to the designer?
