Fireflies and internal light
Do you wonder where fireflies got their internal light? Fireflies actually contain the so-called Luciferin. This substance when combined with oxygen will enable them to produce light. This process is called bioluminescence and they light up to attract the mate. Same is true with angler fish which also produces light, but they use it to catch the prey.Do you wonder where fireflies got their internal light? Fireflies actually contain the so-called Luciferin.
