Strangely enough, even earthworms (Annelids:Oligochaetes) can be bioluminescent. They are one of the few terrestrial organisms which can glow. The species Diplocardia longa found in the Southern United States can be more than a half meter long. It secretes glowing coelomic fluid when disturbed. Other large luminous earthworms are known from Australia. (Photo by Milton Cormier)
