The Effects of a Sting by a Poisonous Coelenterate

Many jellyfish inhabit the tropical and temperate waters of Australia. The majority of stings by these jellyfish result only in local pain, skin welts and erythema. Nausea, vomiting and headaches may also occur sometimes. First aid consists of local application of ice packs or iced water, and supportive care such as analgesia as required.
