Residents of Ocean County are advised to be on the lookout for a rare type of jellyfish with a powerful and painful sting.
The Department of Environmental Protection is advising recreational users of Metedeconk River to watch out for clinging jellyfish.
Clinging jellyfish are not native to New Jersey, but they were previously spotted last month in Monmouth County.
Clinging jellyfish are native to the Pacific Ocean and are very small, about the size of a dime, and difficult to spot in the water.
Their sting can produce severe pain and can result in hospitalization in certain cases.
They tend to attach to submerged plants and algae in areas not usually used for swimming, but officials urge caution.
