(FOX 46 CHARLOTTE) - South Carolina's Department of Natural Resources is warning beachgoers about an ocean threat washing up around shore.
The DNR said a small number of Portuguese man-of-wars have recently been reported on the state's beaches.
A cousin of the jellyfish, Portuguese man-of-wars are highly venomous and cause extreme harm to those it comes in contact with.
"Even a dead man-of-war has a sting strong enough to sometimes require medical attention," DNR officials said on Facebook.
This sea creature isn't just one animal, but rather four types of creatures living together in a colony, according to researchers. Normally man-of-wars exist in the open ocean, but are occasionally pushed ashore.
The good news is they are easy to spot.
"The bright blue 'float' of a man-of-war makes them easy to recognize and avoid."
So if you're headed to the beach this summer season, be sure to stay clear.
