More than 200 people were stung by jellyfish at South Shore beaches over the holiday weekend.

 Jellyfish washed ashore from Jones Beach to Robert Moses – leaving many beachgoers with stings.

Beach officials say said there were “about 200 sting bites at Robert Moses and about 30 at Jones Beach.”

EMTs say pouring vinegar on the sting is a good way to reduce the pain.
