Box jellyfish advisory posted for Ala Moana, Waikiki beaches
Honolulu Ocean Safety officials have issued a box jellyfish advisory at Ala Moana and Waikiki beaches on Oahu today.
The creatures usually arrive 8 to 10 days after a full moon. Lifeguards have posted warning signs at the beaches.
The invertebrates, named for the squarish shape of their bell-shaped body, can cause a painful sting on beachgoers, according to the Waikiki Aquarium.
Many lifeguards and doctors recommend rinsing the area with seawater and then applying a paste of unseasoned meat tenderizer and vinegar to the sting to help deactivate the toxin, the aquarium said.
