The jellyfish, known as the mauve stinger or "purple meany," has been moving along the Jersey Shore and stinging multiple swimmers.
The Department of Environmental Protection has authorized a study in partnership with Montclair State University to determine the distribution and prevalence of clinging jellyfish, a dime-to-quarter sized and invasive jellyfish that packs a powerful sting that has been reported mostly in the Shrewsbury River in recent weeks.
The jellyfish carry a very painful and sometimes dangerous sting that in extreme cases can lead to kidney failure.
Even more clinging jellyfish have been found in the Monmouth Beach and Oceanport areas of the Jersey Shore.
