Blue Bottle Jellyfish

The bluebottle jellyfish is responsible for thousands of stings on Australian beaches each year. Clinical features include intense local pain and dermal erythema. Hot water immersion provides safe symptomatic relief. Unlike Physalia stings in other parts of the world, major systemic envenoming does not occur.
