HARKERS ISLAND, N.C. (QUEEN CITY NEWS) -- If you're heading to any Carolina beaches this weekend, local officials are warning folks about the presence of Portuguese Man-o-Wars. While these striking blue-and-purple creatures might look like something out of a sci-fi movie, their tentacles pack a r eal sting, even after they’ve died. Park officials are urging beachgoers to be extra cautious when walking along the sand barefoot. And yes, that includes curious kids and overly adventurous pets! Tempted to poke or pop that shiny blue float? Just don’t. Officials strongly recommend avoiding any contact with the creatures, even if they appear lifeless. If you or someone in your group does get stung, officials say to reach for vinegar, not water, to rinse the affected area. Officials say vinegar can help neutralize the stinging cells and ease the pain.
