Mechanism

Nematocyst stages of discharge
  • Physical contact or osmotic gradient causes discharge of neamtocysts
  • A spring loaded venom delivery system

Treatment

  • Immerse in 5% acetic acid to inactivate nematocysts
  • Alternatives
    • Immersion in rubbing alcohol (isopropyl 40%)
    • Baking soda
  • Avoid fresh or tap water since it causes nematocyst discharge via the osmotic gradient
  • Antivenom is available for severe box-jellyfish sting
