Like all true jellyfish, the moon jelly’s tentacles are covered with specialized stinging cells, called cnidocytes. The moon jelly uses these stinging cells to hunt small pelagic invertebrates and occasionally fishes and to capture other food particles with which it might come in contact. The cnidocytes are also the source of the sting that people feel when we come in contact with a moon jelly.
