According to local reports, numerous Portuguese Man-of-War (also known as Blue Bottle), a type of stinging jellyfish, have washed ashore in and around Onna Village.

The bluebottle is not a true jellyfish but does have a burning sting. Stings from other types of jellyfish should have sea water poured over them, or vinegar - BUT vinegar should NOT be used for bluebottle stings. Fresh water should NOT be used on stings either, as that could activate the stingers. Symptoms can include swelling around
the lips and eyes, severe dizziness or faints, persistent sneezing or coughing, chest tightness, rapid development of a rash and signs of shock.

Anyone stung by a bluebottle should immerse the stung area in warm water (about 45 degrees Celsius or 116 degrees Fahrenheit) for 20 minutes. Anyone who experiences increasing numbness or difficulty breathing, or showed signs of poisoning or later infection, should see their doctor. Additionally, please ensure your safety by using tweezers or a credit card to pick or scrape off the tentacles. If available, use medical gloves.
