The Box Jellyfish
▶ The box jellyfish predictably visits the warm waters of Hawai'i monthly and is most commonly found on Hawaii's leeward (west) and south shores.
▶ Their arrival on Hawai‘i’s beaches is quite predictable. They usually arrive around 9-12 days after a full moon (but occasionally they have been observed on off-cycle days as well). This is when warning signs are usually posted on many beaches.
▶ Box jellies are found in shallow tropical seas throughout the Pacific, Indian, and Atlantic Oceans. They generally occur in quiet, shallow waters of protected bays and over sandy-bottomed shorelines.
▶ A fully-grown box jellyfish can measure up to 7.9 inches along each box side or 12 inches in diameter, and the tentacles can grow up to 10 feet in length.
▶ Rather than drifting as do true jellyfish, the box jellies are capable of achieving speeds of up to 1.5 to 2 metres per second or about 4 knots (7.4 km/h; 4.6 mph).
▶ Tentacles of jellies and their relative, the Portuguese Man-of-War, are lined with microscopic stinging cells. Each cell fires a barbed thread that can penetrate the skin and deliver a toxin that causes a burning sensation and, sometimes, more severe reactions.
▶ If you see a jellyfish on the beach, don’t touch it as its tentacles can cause a painful sting even if the animal is dead.
▶ They are active predators, capturing small fishes and crustaceans with their potent sting.

What can you do if you get stung by a Box Jellyfish or Portuguese man-of-war?
- Carefully remove (pluck, not scrape) the tentacles from the skin (use a towel, napkin, or other item other than your fingers) and rinse the affected area with vinegar.
- Get medical help in case you suffer from a severe reaction. Immediate medical care may be necessary as jellyfish stings may cause an anaphylactic shock or even death.
- Get the help of a lifeguard or call 911.
