The dangerous clinging jellyfish that began to invade Barnegat Bay in New Jersey a few weeks ago are now multiplying like rabbits in the Shrewsbury River.
Researchers went to Monmouth Beach Tuesday to collect dozens of the jellyfish that have been collected floating freely in the town's lagoons in the past three days.
NBC 4 New York was the first to report the discovery of the invasive species in Monmouth Beach and Oceanport earlier this month. The swimmer who was stung in Oceanport landed in the hospital for two days after being stung by what he thinks was one of the jellyfish.
The sudden population explosion is not encouraging for the Jersey Shore.
"I'm not going into the river for the rest of the summer," said Emily Sgro.
While the invasive creature is turning up in the back bays of New Jersey, the creature has not been found on the ocean beaches.
