They’ve arrived on our local beaches and the SCDNR is warning beachgoers to be aware of highly venomous Portuguese man-of-war.

In a statement over the weekend, DNR said a small number of Portuguese man-of-wars, which are marine hydrozoans, have recently been reported as being seen on South Carolina beaches.

“You should steer clear of these highly venomous relatives of jellyfish both in the water and ashore, as even a dead man-of-war has a sting strong enough to sometimes require medical attention. Fortunately, the bright blue ‘float’ of a man-of-war makes them easy to recognize and avoid,” DNR said.

DNR said the man-of-wars are pushed ashore by strong winds. They have recently washed onto beaches from Florida up to North Carolina.

Portuguese man-of-wars can be 12 inches long and 5 inches wide with tentacles as long as 165 feet.

The tentacles are the second organism of the man-of-war. The tendrils are covered in venom-filled nematocysts that are used to paralyze and kill fish and other small creatures.

Detached tentacles, which can sometimes be clear and hard to see, can sting just as painfully as the live organism in the water and may remain potent for hours or even days after the death of the organism or the detachment of the tentacle.

The sting to humans is excruciatingly painful but rarely deadly.

Nobody goes to the beach to get hurt….so keep your eyes open.
