HONOLULU, Hawaii (HawaiiNewsNow) - Ouch.
Thousands of Portuguese man-of-wars invaded beaches across Windward and east Oahu on Tuesday, in what’s believed one of the largest influxes of the creatures in years.
By 2:15 p.m., lifeguards reported treating more than 200 stings on Oahu.
At Kailua Beach, at least 100 people were stung, and thousands of man-of-wars were counted. Thousands more were reported at Waimanalo, where 80 people got stung.
And at least 30 people suffered stings at Makapuu, where there were about 500 of the jellyfish counted.
Lifeguards have posted warning signs at affected beaches, and are urging swimmers to use caution.
Those who are allergic to man-of-war stings are advised to stay out of the water.
Man-of-war stings are painful, and can leave behind red welts. The tentacles of a dead man-of-war are still potentially potent.
