Fireflies

Fireflies glow from the tummy and look like a sunflower shell. When light is given off by living animals it is called bioluminescense. When they blink they talk but we don't know what they are saying it is a secret code. Even know fireflies are called fireflies there are actually beetles. It starts out like an egg then it turns into a glowworm then they turn into a firefly. It glows for defense it tries to say to the predators like toads that he or she is poisonous then the predator does not like it so it goes away. Only two weeks a year do they blink and mate and have babies. The females stay on the ground and the males are in the air, when the female like what she sees she blinks back and the male goes with the female. The males synchronize their blinking.  luciferase lucifiraine and oxygen make light.
