A fairly intense stinging pain was experienced immediately after tentacle pieces from Chiropsalmus quadrumanus or Chrysaora quinquecirrha were applied to the forearms of two testers. The intensity of the sting from C. quinquecirrha sting seemed more intense than the sting from C. quadumanus. A quite visible area of redness was observed on the skin of both testers within minutes after application of the tentacles from either of the jellyfish species. The intense stinging sensation on the arm remained for approximately 30 min after the tentacle was applied to the arm. The areas of redness remained for up to 24 h on skin that had contact with jellyfish
tentacles (Table 2).
