A rare jellyfish that  has been terrorizing beaches along Long Island and New Jersey beaches is not expected to affect Hudson Valley beaches.

Over the weekend, a smack of jellyfish washed ashore from Jones Beach to Robert Moses – leaving scores of beachgoers with stings.

Wendy Rosenbach, of the New York State Department of Environmental Conservation, says it should be OK to swim here this weekend.  “The mauve stinger is a warm water oceanic species and not a jellyfish we expect to see often in New York’s nearshore coastal waters and it is even less likely in “inland waters” like the Long Island Sound or Hudson River. Recent wind and oceanic currents drove a large number of mauve stingers to New Jersey and the south shore of Long Island where they interacted with bathers. This could also happen in Westchester, but it is not likely. Bathers in the Long Island Sound and Hudson are far more likely to encounter lion’s mane jellyfish which are regular visitors to the area and also sting.”

Experts say the purple and red spotted mauve stingers are particularly nasty since they have sting receptors on their crowns in addition to their tentacles.

Officials have not had to close any region beaches yet because of the jellyfish and their sting is more annoying and painful than life threatening. EMTs say pouring vinegar on the sting is a good way to reduce the pain.
