Rhode Island DEM warns of Portuguese Man o’ War at state beaches

PROVIDENCE, R.I. (WLNE) – The Rhode Island Department of Environmental Management is warning beachgoers to swim at their own risk after Portuguese Men o’ War were spotted on state beaches.

“Abundance is low so far, with just one or two washing up somewhat sporadically on our southern beaches,” said Katie Rodrigue, Principal Marine Biologist from DEM’s Division of Marine Fisheries. “They are likely coming up on the Gulf Stream from southern waters and being brought to shore by southerly winds. This marine event may continue for a little while but is typically short-lived.”

The tentacles of the Man o’ War can grow to 30 feet or longer. They contain venom that can paralyze and kill small fish and crustaceans, according to a post on the DEM’s Facebook page.

The DEM warns swimmers to be on the lookout for something that looks like a plastic bag or balloon floating on the water.

“Once the Man o’ War gets into the surf zone, if the water is rough, the tentacles can break apart and they can continue to sting even while unattached. The sting is very painful and can leave scars on people with more sensitive skin,” said Rodrigue.

If you are stung, the tentacle should be removed by tweezers or a gloved hand. Then, soak the skin in hot water or take a hot shower.
