Clinging jellyfish were first spotted in New Jersey bays 10 years ago, and after a little girl was stung last week, they’re back again.
You may not even see them before it's too late. They’re only the size of a quarter, but they pack enough venom to send grown adults to the ER in crippling pain.
“Clinging jellies are a small, invasive jellyfish about the size of a quarter from the Pacific Ocean,” said Dr. Paul Bologna, the director of the Marine Biology program at Montclair State University, and the leading expert on jellyfish in New Jersey.
First documented in New Jersey in 2016, they've taken up residence from Cape May to Sandy Hook in rivers, bays, and areas of brackish water, but not in the ocean.
Last week, 6-year-old Amelia Colvin was in the Metedeconk River when a clinging jellyfish got stuck between her life vest and skin.
“A young girl was stung and basically spent three days in agonizing pain,” said Dr. Bologna.
After three trips to the ER and doctors' offices and numerous phone calls, it would be five days before the pain finally eased for little Amelia.
Dr. Bologna can't predict just how bad a season it will be.
