Facts about jellyfish stings:

  • Jellyfish have cysts on their tentacles. The cysts contain venom.
  • Contact causes the cysts to inject venom into the skin.
  • The venom causes inflammation of the skin and tissue beneath the skin.
  • Venom may also be absorbed into the bloodstream:
    • Some types of venom are toxic to the heart, nerves, liver and kidneys.
  • Venom rarely causes an allergic reaction.
