Notes
Alatina mordens is a highly dangerous species. Its sting has been associated with severe cases of Irukandji syndrome requiring life support in previously well victims. Contact with this species should be avoided.
Sypmtoms of Irukandji syndrome involve severe lower back pain, nausea and vomiting, difficulty breathing, profuse sweating, and in some cases severe hypertension. Complications can involve brain haemorrage, pulmonary oedema, and death.
If stung, flush the area with vinegar as soon as possible to iinactivate undischarged stinging cells. Monitor the patient for at least 30 minutes; if symptoms develop, seek urgent medical attention.
